From what I understand is, as I did, he got the coin after he started caching. I went back to every cache I found and logged the coin then retrieved it so I could track my miles. You have to leave a note when you drop the coin. I wrote "drop/retrieved travel coin". I was supprised how many miles I've traveled in the short time I've been caching. 3,900 miles in less than 6 months with 115 finds. Don't even want to think about this gas .
