I was at my local coin shop and they just received a crisp 1990 L $10 with a full offset print of the reverse on the front of the bill. Its way cool just curious what something like that might be worth.
It looks like this one, however in the bottom right corner over the ten it appears to have a fold as no over print is on the corner. http://www.ebay.com/itm/1985-10-Err...627852?hash=item25b7ee264c:g:2TkAAOSwe7BWz8PB
It all depends on condition. They range between $50 - $400 Fine - CU for full offset, with most going at the high end of the range if they are CU and a dark offset. Minor offset and/or light offsets are worth less.
A similar bill sold on ebay in May, 2015 for $113.50 http://www.ebay.com/itm/10-FRN-OFFS...D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
