Here is one that I just completed...The 75/75 Club.
It requires you to have 75 D-5 and 75 T-5 caches. I have been working on it since I completed the 50/50..
1. Participating (9-10-2012)

3. Mission Complet: It will be going out today.
4. Mission Received: (10-9-2012)
I will post some pics of what I got a little later.
IMHO, that is one of the original and best ... Go get it!
I bought the Kayaking one when he added them to the list. I was tempted to get this one too, but I don't do alot of climbing. They are very nice coins.
The Moop Along has a 5 star Caching Climbing coin for sale in his Remodeling Sale thread. Go to the last post to find it. Towards the bottom of the list.
