I worked out one heck of a deal to acquire both of these truly beautiful, scarce and amazing pieces today. With a little knowledge of these error types, researching recent sales, an emphasis that few people collect these error types, illustrating a passion to preserve such pieces and that they will be in good hands, and providing proof that I am a collector and not a dealer looking to flip it, it is amazing what you can offer a seller yet they feel comfortable giving it away for a whole lot less than even very recent market value/trends. 1. The 1/2 cent blank planchet is one of only three known total in existence anywhere, according to writeups in Mint Error News. As you can see, it is in absolutely amazing condition (beautiful color and few marks or dings on both sides, great rims) for being at least 161 years old (James Buchanan was in office as President in 1857). Nickels on Cent planchets are rare, and incredibly rare as double denominations; they are very scarce in MS65RD, and even more so from the Denver Mint, which is known to have far fewer errors escape than the Philly Mint. And unlike many nickel on cent double denomination errors, the features are strong for both on both sides, including two very distinct and complete, full dates. Even more cool is that each side has a head and a tail on it! I hope you enjoy them!
