Yes, fair enough not wanting to damage it. I guess I'd think about it this way--with the tick marks and spots on the obv, this coin is only worth face value unless it has a pretty substantial error. If it has a plating bubble, then the coin has a head start in rotting away regardless of what you do. I'm not sure what the market value would be for a die crack of this size, but I'm thinking that it wouldn't be a ton. Full disclosure: I'm not much of a modern US coin error or variety collector. Maybe others will check in with their thoughts and offer better/different advice.
