New Member From Laos(?)

Hello all,
American currently residing in Laos.

I've been living in Southeast Asia for over a decade. Originally joined this site as a last resort to identify what turned out to be a Korean bus token. You guys really know your stuff!

Since being on this side of the world, I've been taking advantage and try to look for old coins every so often. Mostly interested in colonial era, but recently been exploring the idea of collecting junk silver and stacking as a long term investment. Currently more of a collector than a stacker, though.

Some questions:
(Not sure this is the right place for questions)
1-Is there a forum page here for sharing photos to determine whether or not an antique coin is counterfeit? (I'm not talking about silver testing.)
2-Can anyone recommend ways to get junk silver coins? (Is there a reliable online retailer that stackers know of, or should online shopping be avoided, as a rule?)

Cheers all!
