10th International Mathtrade

Recommended Posts

(Most of the following text was written by E&Cplus3 in earlier mathtrades and just slightly changed, thank you Chuck!).

 

Ok, here we go! Sign in this 10th International Mathtrade by sending your info to

 

mathtrade10@web.de.

 

I will need your:

 

- Caching Name

- Real Name

- FULL Mailing Address

- Email Address

 

I will then send you the Link to the spreadsheet, in which you can submit your coins! If you don't get an email within 3 days just let me know.

 

The trade will be divided into four phases:

 

1. Coin submission - entering your trade offers into the spreadsheet (ends May 31st)

 

2. Regroup - reorganize your coin submissions to create groups (ends June 7th or earlier)

 

3. Want list submission - create your wish lists! (ends June 28th or earlier)

 

4. Trading! - trade list generated and emailed to you (starts June 29th if all goes well!)

 

Please respect the following rules:

 

1. This is an international trade - only take part in it if you are willing to pay for a possible overseas shipment of your coins! Remember that in theory each coin that you trade away may have to be sent to a different destination, within or outside of your own country.

 

2. You can list both trackable and non-trackable coins. If nothing is mentioned in the Remarks column, the coin will be assumed to be trackable and unactivated. In all other cases the status of the coin needs to be specified in the Remarks column. Activated coins are only allowed if they will be offered up for adoption (with the exception of Lackey and Moun10bike coins, obviously :D).

 

3. Participants may only submit one coin of any one edition (same coin with same finish/colour/etc) to trade. Duplicates are not allowed.

 

4. Please make sure you adhere to the deadlines shown above! Any edit after a deadline will be ignored!

 

5. Please keep your list to 50 coins or less!

 

 

Keep an eye on this thread - I will use it to post additional information/clarifications whenever needed!

 

Of course you can also use it to post any questions or remarks.

 

 

 

A More Detailed Explanation:

 

Q. What is a geocoin math trade? What makes it different from a 'normal' trade?

 

A. In a ' normal' trade, person A gives coin X to person B and person B give coin Y to person A. Sometimes person A wants a coin that person B has, but has nothing that interests person B to give in return. In that case person A could go looking for a person C to arrange a trade to get a coin from person's B want list. In a math trade you don't have to hunt for a 'person C' -- the software will do this for you! The math trade software will find optimal 'trade chains', some of which may involve just the regular 2 coins, while other 'trade chains' that are part of the same math trade may involve 3, 4, 5 or even more coins.

 

Q. I feel uncomfortable listing coin offers without knowing what I'll receive in return for them. Why would I do this?

 

A. You will be the one to decide what you'll get in return. After everyone has listed their coin offers, you can go through the total list of offers and make a want list for every coin you have offered. If you are not interested in trading one of your coins for any of the listed offers, you will simply use an empty want list for it, so that your coin won't be traded at all.

 

Q. What if someone offers a coin that I REALLY want? Is there a way that I can maybe offer 2 of my coins in exchange for this coveted coin?

 

A. Yes, there is. After Phase 1 (entering coin offers), we will enter Phase 2 (regrouping). During this phase you have a chance to look closely at the coins that are being offered, and if there are coins you would really want to get, you could try and create a more interesting offer by grouping two or more of your coins into one offer. If you group coin X and Y together, then these will not be traded separately, but as one single unit, for which you can decide (during the want list submission phase) what you want to trade them for.

 

(Detailed instructions for this regrouping will follow once we hit that phase (but don't worry, it's actually quite simple).

 

Q. Two or more people have listed one specific coin that I like. But if I include both in my want lists for, say, two of my coins, I risk ending up with 2 copies of the same coin. Is there a way to prevent this?

 

A. Yes, there is (a more verbose answer will follow at the appropriate time).

Count me in.

 

One question though ... once coins are entered into the trade list, if one (or more) coin should sell or trade OUTSIDE the math trade before it is over .... what happens ????

 

... Or are the coins you list in the trade locked in until the mathtrade is complete ???

If you traded coins away that you listed in this mathtrade it is not a problem at all. In your wishlist you have to list, which coins you would trade for each of your listed coins. If you leave your wishlist blank behind one of your coins it will not be traded.

 

Example:

All listed coins get a number. If you have 2 coins in the mathtrade with the number 11 and 12 and you don't have 11 anymore (or there is no other coin that you want to trade 11 for) and you would trade 12 for the coins 123, 234 or 345, then your wishlist looks roughly like this:

 

11:

12: 123 234 345

 

11 will not be traded and 12 will only be traded for the three listed coins.

 

I hope it is clear now (more details will come later).

3. Participants may only submit one coin of any one edition (same coin with same finish/colour/etc) to trade. Duplicates are not allowed.

 

Is it allowed to list a few coins individually A, B, C, and also coins from the same series as a set A+B+C, or will it be treated as duplication?

Well, in the last mathtrades you had to list each coin individually. After the submission phase you are allowed to group coins together. According to the rules and with this in mind it would not be allowed to it like this. But I don't want to take everything too serious, so if no one else mind?!

At what stage - if any - will photos for each geocoin be available?

It is not obligatory to post pictures of the coins. But in the past some people added links to fotos io increase the chance that other people wanted to have those coins.

My 36 coins are added! Some rare Norwegian geocoins in there (one of which was given to me by one of Santa's little helpers, on behalf of Santa... :anicute: ). I'll try to add links within the next few days.

I have 39 coins added (*i think*), with the other 11 sitting on my desk to add when I get home from GW.

 

Just so everyone knows, any and all of my coins are available for trade anytime. Before, during, or after the mathtrade. If you see something you just have to have, email me. As long as I haven't submitted my wish list, I can blank it out to not trade if it's already been sent out in a trade. If they don't trade, they'll all be available after.

Ok, oficially the submission phase is closed (if you want to submit more coins let me know as soon as possible).

We ended up with 23 participants and 646 coins for trade!

 

Now the Regroup Phase begins (the Regroup Phase will be open until next Saturday June 7th, 9:00 PM EST )

 

What is regrouping about? Again I want to use Chuck's explanations:

 

... If you are interested in regrouping coins to make an extra special package in the hopes of landing that one must-have coin, then follow the instructions below. When you are satisfied with the way your coins stand, please let me know via email or a post to this thread. Remember, regrouping is optional. If you simply want to trade your coins off one by one as they are now listed, all you need to do is send an email to the address below saying that you are done regrouping. If everyone finishes with the regrouping early, we can move on to the Want List Phase early.

 

Regrouping Instructions:

 

The Regroup Phase gives all participants the chance to create sets of two or more of their coins. You can do this to make an offer more attractive to others (and therefore to have a potentially higher chance to get a specifically wanted coin). Remember -- if you decide to group two or more coins together, these will only be traded as a complete set (or not at all).

 

To regroup your offers, please send an email to:

 

mathtrade10@web.de

 

containing the line numbers and the coin descriptions of all coins for each coin set you want to create. Also mention your geocaching.com nickname -- just as an extra measure of insurance to keep me from making mistakes.

 

-------------------------------------------

Example:

 

Let's say I have seen some must-have coins that I, well, must have. Unfortunately, I feel that the coins I am offering -- on their own -- won't seal the deal. So I decide to combine some of my coins into sets. I'll fire off an email with the required info:

 

Regrouping for E&Cplus3:

 

Group1

ID 160 DNA Geocoin gold

ID 161 DNA Geocoin silver

ID 162 DNA Geocoin copper

ID 165 DNA Geocoin antique silver

 

Group2

ID 177 Tennessee Micro 2008 nickel

ID 178 Tennessee Micro 2008 gold

 

Please use the ID's as listed on the USE THIS COIN SHEET worksheet in the Mathtrade10 document.

Make sure you only use the numbers in the column titled "REFER TO THIS COLUMN ONLY!"

 

Please let me know if you have any questions about this process. You can post your questions here, or email them.

No regrouping ATM either. But I'd be flexible to regroup on the fly if that is necessary and possible at all later on.
