The PCGS U.S. Coin Forum COMPUGRADE Thread
After receiving some feedback, have decided to try and make this the All Things Compugrade thread.
Interesting information about Compugrade posted here will be copied to the OP to make it easier for people to find information about the company and their products.
Anyone have a Compugrade slab containing a coin other than a $20Saint, Morgan or Peace Dollar?
Could the Forum put together a set of pictures of all grades 60.0 through ???
Compugrade Samples - All are hard to find. The 2 samples on the outside are the ones mose often seen. The middle one has the style of 1967 label but with a 1969-D Kennedy, the only one I've seen. Are there others?
Compugrade boxes are few and far between. This one was acquired 2/19 off ebay, the seller including it in a 7 Compugrade coin BIN since the seller no longer needed it after selling all the Comugrade slabs they had!
Link to the Compugrade patent, thanks to BStrauss3.
In the patent is this illustration showing how the evaluation of a Peace dollar is broken down into numerous tiny segments.
Here's a strong start to the grading set goal posted by astrorat and reposted here - have heard about it for years and glad to finally see it shared on the forum! This will be a strong start to developing a picture grading set!
These Saints were acquired April 2021. They are the only ones I have ever seen. Please post if you have other Saints or type coins.
Have finally figured out letter codes on this slab (picture courtesy of astrorat) based on the ad's posted here.
L = Luster
P = Proof like quality
C = Cameo strength.
In reading the ads and patent, not sure what scale is used for each letter. Does anyone here know?
Compugrade Ads - Originally posted by LostSisler who currently owns the rights to the "Company" and reposted by U1Chicago here from a thread originally started in 2014 is the Saint ad. In reviewing the Numismatist archives, the first ads are from 1991, the last ad by Compugrade in the Numismatist is the Saint ad from May 1992. Later ads referencing Compugrade, through roughly 1994, include ads by Heritage soliciting consignments and accepting Compugrade coins.
