Msl2196 the coin case I have is a 3 piece case I've ordered off eBay for a few bucks a piece. You order them by the mm size of coin They are very similar to the NGC/PCGS hard shell cases. I've heard if you send henning into the NGC company they will not grade them and return with a tag or paper notation explaining this item is a known contemporary counterfeit. I've also read in a thread somewhere else there is another lower name grading company that will actually grade henning nickels but due to the coin being cast counterfeited off worn nickels the grades arent ever going to be high numbers also grading is to determine a value on the item it doesn't seem practical to spend the cash since there's no really know mint history value.
