I have only dealt with Gainesville coins F2F at some of the local coin shows here in Mass and NH. They say there "Affiliate", There receipt is from GC if you would like one, there email it to. They use the best pricing from there web site which is nice. There is usually a couple of them working there both very friendly. They usually have alot of bullion stuff none of the other dealers have. Including tons of Perth and NZ fancy coin stuff, Lots of World silver bullion, This week they had SAE 3.75 over, Maples 2.80 over,Taku's, 13' Pandas $6 over in full sealed 30x sheets if I wanted, looks like they had 3-4+ sheets and plenty of everything else. Stack of 10x10g Valcambi silver and 100 x 1g AU. All Perth bullion including 1 KG of Kook, Koala and Snake. They usually have more gold bullion then any one else with Lots of Pamp 1g through 1oz, GAE, Gold Maples, lots of Perth gold reg and Lunar to.
Thumbs up with my experience with them.
The License thing has made me think a little.
but doesn't/didn't really bother me.
