Here is a Roosevelt dime clad blank planchet error offered with no reserve. This coin was never struck by the US Mint and it exhibits high grade gem uncirculated surfaces and great eye appeal as seen in the pics. BE SURE TO SEE THE OTHER ERROR COINS that I am auctioning right now that also feature low starting bids and no reserve price. Keep watching my auctions for more NGC and PCGS investment grade certified errors. Shipping and handling is FREE. Good Luck.
2)USA error blank of 1 presidential dollar coin
999 Normal Presidential Dollars and 1 Error Coin
Blank Planchet is 1 in 1,000 Find
.A blank coin was the only error found in this box of 1,000 Washington Dollars.
.Here’s another photo of M.S.B.’s blank coin. The 999 normal dollars depicted with it are a reminder of just how hard it is to find error coins in bank-wrapped rolls. I searched through 6,000 plus Washington Dollars and found only a few very minor errors: a cracked clad layer (with a very teeny crack running across the face from rim to rim) and half a dozen embossed letter types (which some people persist in calling “dropped letter” types when they are not!) I have an article that explains the difference between dropped letters and embossed letters.
2. Malaysia 20 Cents Error Blank Planchet
photo: Malaysia 20 cent blank planchet
I bought this piece of error coin two years ago with price of RM10 from a McDonalds franchise manager. He told me that he got a lot of foreign coins in their McDonalds donation box and this coin was one of them. Even he found a Half Cent of Queen Victoria inside the donation box. I wonder if Singaporeans really had foreign coins inside their wallet. Usually they will take only banknotes for donations purpose and the coins will be used for their changes. That is quite not honest. Then, he as the manager will filter the coins by taking out foreign coins.
The dimension and weight of this coin match the dimension and weight of Malaysia 20 cent. If this error coin is genuine, this is categorized under the blank coin type. There are many types of error coins, such as double strike, wrong planchet, off centering, low strike, off strike, mirror strike and others. From my survey at the Internet, blank coin error coins are the easiest to find compare to other types.
There are two types of blank coins. The first type is without raised rim on it. In this case, the coin is better called as blank coin, as it never involved in any of the coin minting processes. For the second part is with raised rim on it,blank planchet. A planchet is a blank coin that is ready to be stamped by an engraved die. I think my coin here has raised rim on it. The raised rim on the blank planchet means that the coin has undergone at least one process of coin minting, which is softening process. I think softening process soften the surface of the coins to ease the stamping process later.There is probability the blank planchet escape the pressing section and then bagged for circulation.
Counterfeiting exist easily because blank coins are easy to copy and produce. There are few tips on how to differentiate between a genuine and a fake one. First, if the blank coins has milled/reeded edge, most probably it is fake, because milling of the edge and stamping usually occur simultaneously for conventional minting. By the way, one of the objectives of reeded edge is to avoid counterfeiting. Second one, usually blank planchet has smooth and shining surfaces. If the surface is rough, maybe someone had sanded and polished the surface of the coin.
