How and How Not to Describe Bottom-Tier Slabs

Our top houses are almost always the most forthcoming about the quality of coins in bottom-tier holders. Some houses, however, continue to violate numismatic rules.

The example below cites PCGS retail prices for a 1903 Morgan dollar worth about $130 … and only if not cleaned, which this example just might be. The auctioneer cites a ridiculous $3,600 price.


Here is how top-house Jewelry Exchange handles the same situation, noting it cannot guarantee the grade because of the holdering company’s grades may not meet industry standards.


Several of our top-ranked houses treat bottom-tier and self-slabbed coins in the same manner, earning our trust.

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.
