I had an opportunity to view this cool coin. The owner wants to know what the value is of such an error?? Not being an expert on pretty much of anything, I come to you for an answer. I think it would be up to the potential buyers of such error coins. Comments?
I don't think there are established values for the issue. The rule is that it is worth whatever a collector of such an issue is willing to pay for it. But it could demand a good premium. I no longer collect mint errors but there was a time that I would of paid maybe $30 - $40 for a huge Planchet Lamination such as that neat example. Great eye appeal is important.
