Found this on EBAY. Isn't this the same error that the one member (can't remember his name) here on CoinTalk has? http://www.ebay.com/itm/300715526269?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
redwin is his name, and yes it is similar. But, this one on eBay is graded by a reputable TPG, and redwin's is not. Though, redwin will tell you that his is special because you can read both dates. Oh wow did you just open a can of worms!!!
Oh that's just dandy. Didn't mean to do that. Was just wondering if it was like his or if maybe it was his.
The NGC coin is probably showing both dates as well since the slab label identifies it as a 1990 cent struck over a 1990 P dime. Any dual denomination strike over is cool. Even better are the ones with both dates. But the ultra cool ones are the ones with two different dates.
Yes, the ones with two different dates would be ultra cool for sure. Seems like the odds of that happening would be astronomical. The error would have to occur in January when the first batch of the new years coins were being minted.
Or in December when they sometimes strike a stockpile of coins to have ready for the first of the year. It doesn't happen often but there are a few dual date dual denomination pieces around. You know what would be the ultimate? Now as far as I know this doesn't exist exist, and if it did I would be sure it was "helped". A dime planchet struck by cent dies, and then struck again by nickel dies of a different date. A dual date, triple denomination off-metal (because the clad composition doesn't go with either of the sets of dies that struck it).
