My experience was in selling them some old family silver today. I think I visited them many years ago when they were more of a coin store. Today they seem like more of a bullion transfer...

Not a serious buyer. When I asked him if he bought silver certificates, he said yes, but he only paid about $1.50 for them. He did not ask the year, the condition, anything. This is kind of nutty...

Weird place. Looks closed. Walk through a dingy alley No thanks. It looked scary especially for a place that deals in money.

Horrible experience with them, don't take your business here, bonanza coins is far far better

Just left the store. They were so friendly and kind and helpful. They chatted with me and gave me a fair price.
