These guys/gals are great. I messed up original order, they corrected my mistake w/ no problem at all. Their pricing is fair, the customer service is really unmatched compared to what I've seen w/ "on line ordering". You folks need a quality product w/ even better service, you just might want to put these folks on your list.

Not much to add to the 5 stars, I got three sets at a fair price and they shipped without delay. I don't usually write reviews but after opening up the excellent and protective packaging I was motivated enough... First time buying from here, but seems like a solid company who's got their act together.
I was searching for 2012 thru 2015 American Silver Eagles in proof condition. Proofsets.com popped up at a fair price [AMPEX and Amazon.com were not competitive], but I could only find the two sitejabber reviews which precede mine. I debated whether or not to go with an unknown [Proofsets.com], but I'm glad I did. The coins arrived in 5 calendar days [in a solid box within a USPS Priority waterproof envelope] as advertised. There was no sales tax and no cost for shipping. I will use Proofsets.com again.
