There have been a lot of Chinese counterfeits coming into the coin market over the last 5-10 years, and occasionally error coins have been the target. Recently, we came across this lot of double-struck Morgan dollars on eBay, with a "Buy It Now" price of $135. They were being sold as "copies" and not as genuine, but the problem comes from them not being marked in a permanent way as being cop …

It is surprisingly how many people still use vinyl 2X2 coin flips to store their coins. Dealers and collectors alike are guilty of this, and the result are coins with a light hazy film of green PVC residue across the coin's surfaces, and sometimes even permanent damage to the coin.

Beware of the many fake coins struck on nails on eBay. They came out after a dime on a nail recently sold for over $40,000 at auction, and these counterfeiters are trying to rip off collectors with these fakes.

There are of course some areas of weakness, and as a whole the error coin market has dropped off from some of the strength it was exhibiting several years ago, but overall we are happy with the a …

Collecting by Error Type There are some collectors who like to collect error coins by “error type.” Most of the time, they are looking for examples of that error type on any and all series of coins, but sometimes they also want to collect an error type for a particular series of coin. This is an exciting and pleasurable way to collect errors since pretty much every coin is visually diff …
