GreatCollections offers bidding advice for newly registered buyers and sellers. Check out the details by clicking here.

GreatCollections offers collectors an extensive selection of certified coins ranging in price from $25 up to $10,000s. All coins have been professionally listed and imaged by GreatCollections expert staff and most are certified by the leading third-party grading companies including PCGS and NGC. Since GreatCollections has possession of all items being offered for sale, GreatCollections will ship your auction winnings and purchases to you securely and promptly. Sellers consign to GreatCollections to take advantage of our low commission rates, which work out in most cases to be cheaper than if they did all the work themselves.

The site also is educational, just like Proxiblog. For instance, you can access a numismatic glossary or discover new ways to bid online and win lots.

Proxiblog stands by claims of fast payment, as we often purchase raw coins on Proxibid, slab them at PCGS or NGC, and sell them at GreatCollections. We also correspond regularly with and cite founder Ian Russell in our numismatic articles for CoinWorld.

If you have any questions about consigning or what your coins are worth, please do not hesitate to contact GreatCollections. Telephone 1.800.44.COINS (+1.949.679.4180) or e-mail

GreatCollections and other sponsors of Proxiblog have the opportunity to donate to our scholarship fund to help educate and inform the next generation of bidders. We publish Proxiblog for free to inform bidders, consignors and auctioneers about best practices. If you believe our site has value, won’t you consider making a donation? Click here to do that entirely online at a secure site hosted by the Iowa State Foundation.
