This is the second installment about the need for coin auctioneers to understand grading. The first listed the Do’s and Don’ts of grading. This cites houses that described raw coins so accurately that PCGS, the most rigorous holdering company in the business, agreed with their grades when Proxiblog sent the coins in for authentication.

We have had similar luck with certain auctions sending to NGC, among them, Manor Auctions, Kreuger and Kreuger, Key Date Coins and Engstrom Auction. We have come close on occasion at NGC or PCGS (within a point) with Western, Weaver, Arneson, Meares, Scott and Kaufman auctions.

Proxiblog is an independent entity with no connection to the auction portal Proxibid. Our intent is to uphold basic numismatic standards as established by the American Numismatic Association and the National Auctioneer Association and to ensure a pleasurable bidding experience not only on Proxibid but also on similar portals such as iCollector and AuctionZip.
