No problem, they also deal with some foreign coins, but mostly Thai coinage. You can see further in the catalog,

Most of the valuable flat coinage is from Rama 4 or 5 reign (like in the 1800's). I have been to the eurseree auctions and the staff is quite friendly and will meet and talk with you. Vituun (as I recall) is the owner/operator, quite friendly, the auctions are also enjoyable and not a rip off. Most recent catalog is here: http://sale60.eurseree.com/

I agree with the folks saying to sell in your home country and buy it back here. Had some gem dealer friends who used to have some African contacts bring some gold in for them, they would make these like 2 1/2 ounce (5 baht) or heavier simple bracelets because that is jewelry but with 1/2 kilo it just isn't worth the hassle, especially since it is fairly inexpensive to sell and then rebuy here. Gold shops are really good place to buy, price is posted and you can order larger size bars, like 5 or 10 baht, or they often stock the 1 baht size.
