A word from the CEO

A proof of Concept is no easy feat and especially so when it comes to numismatic grading. So many nuances and so little time but, the proof now exists, and grading automation is on the way. What is stunning to me is the extraordinary accuracy deep neural networks and artificial intelligence bring to the numismatic industry.

It is my belief grading automation will bring more collectors to the industry but that’s not all because DNN/AI provides unprecedented counterfeit detection capabilities. At nano level, nothing remains hidden. For example, A Morgan dollar has more than two hundred million datapoints. When Coin and Card Auctions scans a counterfeit numismatic into our system, we have captured its digital (measured) topography. It becomes a simple matter to numerically compare a known counterfeit measured topography against any other to determine authenticity.  Its technologies like this that are the future of the numismatic industry, and we are glad to have the opportunity to lead the way. 

A Little Pre-IPO Startup Company With Big Solutions Develops First of Its Kind Proof of Concept

It is no secret that numismatic and sports cards collectibles third party grading has not kept up with the latest in technologies, so a potentially market disruptive artificial intelligence and deep neural networks Proof of Concept (POC) should not be a surprise, but it is to some. Automated grading is possible and with it comes market stabilization, counterfeit detection, digital fingerprints, and emerging marketplaces says the company CEO

PRESS RELEASE  DEC 7, 2022 08:00 EST

DES MOINES, Iowa, December 7, 2022 ( - December 6, 2022 ( - Coin and Card Auctions successfully developed deep neural networks and artificial intelligence (AI) Proof of Concept (POC) for numismatic grading. The company believes its system paves the way for automated grading with unprecedented accuracy and speed.

"Grading and authenticating a numismatic coin, art or sports card can take days or even months. Coin and Card Auctions deep neural networks and artificial intelligence recognizes differences in each numismatic coin using industry accepted grading standards while generating its own digital signature, or "fingerprint," in hours. This system simultaneously saves collectors time while also crushing counterfeits as the system finds and classifies tens of millions of data points on each coin. Besides stabilizing third party grading and providing counterfeit identification the technologies pave the way for automated grading and eventually the development of Smartphone IOS and Android applications having the ability to provide "Point and Click" numismatic identification and grading with instant "go to market solutions" that bridge conventional and emerging marketplaces worldwide. The same technologies can apply to numerous collectibles besides coins, sports cards and art.

Each digital fingerprint and image topography mapping is tens of millions of pixels on a per-coin basis. A single Morgan Dollar topography mapping can exceed 200 million pixels and this precision is why digital fingerprints are expected to be used heavily in the conventional marketplace and rapidly emerging $400 Billion metaverse collectibles marketplace.

Coin and Card converted a patent pending into an international patent filing in August 2022 and plans on converting another patent pending as a follow-on international patent filing during the first quarter of 2023, I am so proud of the amazing talent, hard work and dedication of all those who have helped to get us to this point and look forward to continued successes as we move forward said its CEO, Mike Johnson.

About Coin and Card Auctions

Coin and Card supplies technical solutions to grow and enhance the sports cards, art and numismatics industries.  Numismatic industry active participants average 62 years of age with younger ages engaged in in a growing sports cards market and art collectors age groups are still stable. But modern technologies supply unique opportunities for all ages. Imagine taking numismatic collectibles, art or sports cards and combining them with digital fingerprints registered as intellectual property on the blockchain with smart contracts that pay consumers shared royalties which automatically trigger on resales. Now you have physical assets, IP and consumer shared royalties as a function of marketplace cost vesting consumers themselves in the marketplace. A secondary marketplace for royalties' aggregation is likely soon.

The company's world-class personnel, including Fortune 100 experienced industry experts and numismatics experts, will use the technology to eradicate counterfeiting, stabilize grading, and supply a safer marketplace to collectors. The technology is patented and designed to automate numismatic coin and sports cards grading with consistent and correct results and supply unique digital fingerprints and third-party methods of authentication. 

Coin and Card Auctions deep neural networks and artificial intelligence (DNN/AI) technologies process measured height, color and surface roughness extracted data from professionally graded numismatic coins, art and sports cards and reverse engineers the data to industry adopted grading systems and ISO standards of measurements based on American Numismatic Association grading guidelines and third-party industry-accepted NGC, PCGS, ANACS and other applicable grading systems.  Each digital fingerprint is wholly unique to the underlying physical asset and third party verifiable. The future is here. Join us today

I have a few questions about the details revealed about the scanner used for the coins. I am doing some research on processes used by the US mint. Does this scanning process give details with a precision close to (.001) 1 thousands of an inch? I have done overlays but now I would like to do 3d overlays. Is this possible? Thanks James Elliott

Hello James Good questions. The outputs are nano level, and we use 1.5 microns and 2.5 micron both of which are measured to .001 of an inch. 3D results from measured data outputs unlike 2D images although there are ways to convert and step down 3D/2D data outputs

Hello, I have a 1942 S Lincoln Penny that weighs 2.7 Grams , normal weight is 3.11 +-.13 . Not magnetic and shows no evidence of plating, Brass, Zinc, Silver or Mercury. Is 18.96 mm. in Dia. The "T" in Liberty looks skewed. Not extremely worn, can see lines in Wheat. Any thoughts would be appreciated.

Response to Kevin Folsom - the best I can direct you to is a post by the Numismatic News which does address a similar occurrence in a 1943 Lincoln Cent. I tend to think a XRF analysis may find metal content is affecting weight. It's possible you may have a test or experimental planchet. If it helps, here is the Numismatic News article.
