If I'm understanding you matie!! those coins are only trackable at the www.texasgeocaching.com) you mentioned, I myself- when I get coins that aren't Geocaching.com trackable (that I buy) I buy a TB tag too. and associate the tb# to the coin so it becomes a GC TB- go look at my profile and you'll see what I mean ( I have 2 coins like that and a few more soon!!)-- I'm in the process of get a little treasure chest with all my coins and other tid-bits to share for Icon Ho's!! ..when I get it completed I will try to get a photo up to show it off...
