Super new to the coin collection world but came across this coin through a friend and ended up picking one up the other day. After looking around at other coins this coin is selling all over the place for upwards to $800. Looks like theres only 30,000 but what makes this so special? I heard rumors that there were 1000 that had been autographs? Should I open this and find out? Should I open it and get it graded?
