We just returned from our visit with Kevin at Valley Gold Exchange. Very personable and very honest. Our experience was first rate and we learned a lot.

Very outgoing, felt very comfortable. Left feeling satisfied that I was getting a good deal, and not getting ripped off like most places.

I used to buy silver from these guys but not anymore. I undersrand there are two owners, an American and a foreigner. The American will treat your fair but the foreigner will try to rip you off. I do not want to haggle, I pay spot plus a reasonable commission.

My watch broke and these guys fixed it in like 10 seconds. Didn't even charge me a dime. Really great straight shooters here.

Not a bad shop; quite small. Kevin's coin selection is direct to the point and for both stacker and numismatic buyers. Not full 5 star because selection varies based on clientele selling silver. Has very competitive pricing per ounce over spot
