You have come a long way from not being interested in error coins to considering this one. There is just something that grabs you with this variety, does it not? I don't have a 42/1, but for the right price I would love to have one in my collection. But I agree with others, $500 doesn't feel right on this particular coin. Be careful as lots of counterfeits exist. If you have a dealer you can trust 100%, then don't bother with a slabbed one (I'm not big on stabs in general). When the right coin comes along for the right price, you'll know it. Best of luck to you in your search!
