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.
