I can't find the listing number now, I probably deleted it in disgust. But, one seller was offering a "slabbed" (brand x slab) Flying eagle (I forget the grade) 1858/7 for sale. I e-mailed them that 1) the grading service graded the piece too high, 2) it was a small letters variety, 3) the overdate was on a large letters, 4) all of the diagonistics were missing (broken wing, etc.) and 5) this wasn't an overdate. Strangely (LOL) they never replied to me. I e-mailed the buyer to warn them, but never got a reply. Oh well, let the buyer beware.
On the 1858/7 there is a closed auction from SEGs(AU-50), but how could you see anything on those pictures(if that is the correct auction)? I could point to a lot of silly auctions or prices on dealer sites, but I just tend to skip most of those. For starters just search for SGS on ebay.
definately not the dumbest, but: 1945 D Liberty Walking Half Dollar - Good to About Fine Item number: 190052243681
I have a feeling that the seller does not know how to grade coins, given the fact that his coin has better details than a fine.
That is better than someone who continually lists several hundred coins and states "I know nothing about coins, but this one is certainly a MS60 coin". The coin pictured is something in the AC(about crapy) range.
While not exactly stupid, they guys are funny: ebay: 1883-H CANADA FIVE CENT COIN...$65000.00 B/O Item number: 330050580571
Any listing where the terms and conditions are longer than the item description (although I've been guilty of that myself) or the T&Cs use more than one font and/or color. Any listing that implies that this coin would be worth (insert amount) if only it were in the condition that it isn't in. Any listing where the image is less than the actual size of the coin. Any listing with more than three or four exclamation points!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
1875 Sitting Liberty Quarter Dollar Silver Item number: 120046254086 Seems to be some what normal listing? Yes, but it was for a 20 cent piece.
