First off, welcome to the site! As far as getting it graded, from a financial standpoint it would not be worth it. Getting it graded will not increase the value of the coin. It's probably a $25-$30 coin now, and wouldn't be worth much (if any) more in a holder. Would Libertycoin be kind enough to give you some free advice about the coin? Probably but hard for any of us to say for sure unless we worked there. If I were you I'd just keep researching online and soon enough you will probably understand why its not worth sending in.
