Numismatic crime is rising at an unprecedented rate.

Today, record gold and silver prices attract professional criminals and organized crime groups. As a result, these criminals target dealers, collectors, and coin shops nationwide.

Because of this surge, victims often suffer severe financial loss. In addition, they experience emotional stress and long recovery times. Unfortunately, many investigations stall. Law enforcement agencies usually lack the specialized numismatic knowledge required for these cases.

This is precisely why the Numismatic Crime Information Center (NCIC) matters.

Every day, NCIC delivers free investigative support to law enforcement, dealers, and collectors. Moreover, NCIC provides expert numismatic identification and issues nationwide crime alerts. When numismatic crime occurs, NCIC often becomes the first call that pushes a case forward.

However, as criminal activity increases, the demand for our services also grows. At the same t…

In the world of modern U.S. coinage, very few circulation errors have achieved true landmark status. One that consistently stands above the rest is the 1982 No-P Roosevelt dime, a coin struck not in the distant past, but during the early 1980s, when millions of Americans were actively handling change every day.

That timing is crucial to its appeal. Unlike classic rarities that disappeared generations ago, the 1982 No-P dime entered everyday commerce. It passed through banks, amusement parks, vending machines, and cash drawers before collectors realized something was wrong. Today, it stands as the most important circulation-strike error in the Roosevelt dime series and one of the most significant modern Mint mistakes of the late 20th century.

Despite its modern origin, the coin possesses every trait collectors prize: a simple and understandable error, a direct link to Mint procedures, a discovery rooted in…

When collectors speak of legendary numismatic icons, the name Croesus stands tall. Known for his immense wealth and innovation, King Croesus of Lydia changed the course of monetary history in the 6th century BC.

Counterfeit U.S. coins are nothing new. But in today’s market, modern Chinese-made fakes, often housed in convincing counterfeit holders, are pushing the boundaries, and threatening unsuspecting collectors at every level.

This article highlights just a few of the Carson City (CC) dollar counterfeits currently circulating, many of which were reviewed during a FrostByte “Chit Chat” session on December 7th. These fakes aren’t just poor reproductions; they’re often sophisticated deceptions that exploit gaps in collector knowledge and marketplace oversight.

Let’s dig into some examples, and more importantly, how to spot the red flags.

The “Impossible” Seated Liberty Dollars

Among the most glaring examples are Seated Liberty dollars allegedly from Carson City, but dated before CC coins were ever struck.

This is a  historical impossibility. The …

A spectacular, historically significant, unique set of Martha Washington Quarter-sized test pieces, struck circa 1999, offers a rare window into how the United States Mint experiments with coin finishes, compositions, and surfaces. Not only are these pieces officially documented, but they also represent five distinct experimental finishes, two of which later entered mainstream U.S. coinage.

Listed on the USPatterns website and assigned Judd-2116, these test pieces were struck in cupro-nickel clad and certified by NGC. More importantly, the set remains unique, making it one of the most intriguing modern pattern discoveries available to collectors.

Five Experimental Finishes Tested by the U.S. Mint

This exceptional set consists of five Martha Washington quarters, each struck with a different experimental finish. At the time, the U.S. Mint explored surface treatments to improve durability, aesthetics, and long-term performance.

By CoinWeek

Few U.S. gold coins inspire as much curiosity as the 1887 Liberty Head Half Eagle. At first glance, it appears to be just another late-date $5 gold piece from the With Motto era. However, a deeper look reveals something far more compelling. In fact, the 1887 Half Eagle stands alone in American numismatics as the only Proof-only half eagle of any design type.

That singular distinction raises an obvious question: why?

Despite decades of research, no definitive explanation exists. Nevertheless, when the coin is placed within its broader historical, economic, and numismatic context, the story becomes clearer. Moreover, its rarity, pricing structure, and long-term collecting potential make the 1887 Half Eagle one of the most intriguing Proof gold issues of the 19th century.

Few early Walking Liberty Half Dollars tell a clearer story than the 1917-S Reverse Mintmark issue. It represents a turning point in Mint policy, a subtle design change that created one of the most studied varieties in the series.

Now, a PCGS MS-65 example with a CAC Green sticker brings that history to market in a GreatCollections auction ending December 14 at 5:45 PM Pacific Time.

For collectors of early Walkers, this is the kind of coin that deserves close attention.

A Year of Transition for the Walking Liberty Half Dollar

When Adolph A. Weinman’s Walking Liberty Half Dollar debuted in 1916, branch mint coins carried their mintmarks on the obverse. That placement did not last long.

On February 14, 1917, Mint Director F.H. von Engelken ordered the mintmarks moved to the reverse. He believed the obverse mintmarks looked like die defects a…
