I was watching an auction over the weekend and they had a 16D in AU condition and a 42/1 D in uncirculated condition. Neither coin was slabbed which I found to be odd. The pictures of both coins were well done and met their descriptions. The 42/1 D was the first of the two coins on the auction block. It sold for $1000 and looked to be a coin anywhere from $900 to $5000. Why not slab it and know for sure what it was worth. The 16D sold for $3000 and looked to be a minimum of a $5000 dollar coin. Again why not slab it to see what it was worth. Both the coins were the best I have ever seen for sale, but way out of my league. Any thoughts as to why they would take a chance by not having them slabbed?
The auction was held in Dallas. They also had 3 slabbed Mercuries. 1936 PCGS MS65 sold for $50 (a little high), a 1937 ANACS PR66 sold for $170 (again too high), and a 1942 ANACS Proof no grade for $100 (also too high).
Likely because then the problems would be listed or it would be called a counterfeit. There's generally a reason why such things remain raw and almost none of them are good for the buyer
