It is possible to mess up your listing by 2 decimal places. I recently noticed a coin offered for $42,500 and I was pretty sure the poster was looking for $425.00. I sent a note, was thanked and it was corrected in the listing (it was still overpriced).
Something tells me that might not be what's going on with this listing.
Entertainment value is worth at least a buck, though someone who has done that much research would probably be offended.
