Viewers of Coingrader Capsule know we test modern holdering companies, especially against the widely held half-truth / half-myth that early graders were more conservative than those of today. You can view several posts about that in Coin Update. Here’s one of the first that I did in 2011, titled “Old Green Holders” [ain’t what they […]
Grading Capped Bust half dollars
Grading Capped Bust half dollars is a challenge, especially to new hobbyists unaccustomed to the series, which ran from 1807 to 1839 and which continues to be popular because many of the dates are affordable and come with a large selection of die varieties (including overdate strikes). We’ll save overdates for a future column. This […]

NGC/NCS Announce “Customer-Friendly” Fee Structure
Each year about this time the main holdering companies announce changes to fee structures, typically trying to hold the line for hobbyists while ensuring their own bottom line. Last year, for instance, PCGS announced a “Gift to the Hobby,” ending the annual $149 subscription fee to www.PCGSCoinFacts.com. This year, Numismatic Guaranty Corporation (NGC) and Numismatic […]

Crack-outs Bring Mixed Results
A regular feature of Coingrader Capsule is the cracking out of slabs by lesser holdering companies to see how they do in the big leagues, namely, PCGS or NGC. Specifically, I wanted to test some coins slabbed by National Numismatic Certification, which I reviewed in September, stating that its grading was inconsistent but, on occasion, […]
Computerized Grading, Part 3: What a Startup Might Look Like
So far, we have covered why an impartial and automated grading option would be beneficial and how the machine itself could possibly function. Unfortunately, I do not foresee any of the current major grading companies working to develop this level of technology. It would be irresponsible of them to try. Building a computer that can […]
Review of National Numismatic Certification
Increasingly I have been seeing slabs by National Numismatic Certification, a Florida firm, whose coins I sometimes bid on despite its grading being inconsistent at times, with flaws that would disqualify coins at PCGS or NGC.
