Untrustworthy Estimates

Check Certs and CoinFacts for True Value!


We are so weary of seeing Proxibid newbie auctioneers believing they can guess at values and then charge high fees on top of that.

This is one example of a Proxibid house that consistently overvalues coins, charges 18.5% buyer’s fee, does not combine shipping and charges $12.95 for that. Below is a $50 coin valued erroneously as $150-$200. How do we know? Let’s learn–a lesson for auctioneers and bidders alike.

PCGS Retail Value for this specific coin


Take the certification off the PCGS label and then check retail value at this link.

CoinFacts Auction Prices

CoinFacts shows recent auction prices for same coin at Teletrade, Heritage Auctions, eBay and Great Collections.

We never bid on any lot without checking CoinFacts. We suggest you refer to this databank if you are an auctioneer estimating values of coins certified by PCGS, NGC, ANACS and ICG. DO NOT CITE COINFACTS’ VALUES FOR RAW COINS OR BOTTOM-TIER HOLDERS!

Sooner or later, buyers will learn how much they overpaid on some auctions on Proxibid. We rank our favorite sellers to the right because they don’t use those tactics. As always, though, with any seller, we caution that your experience may differ from ours–but not when it comes to verifying values.

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.
