Some one just bid $4,850 for this coin on eBay. It attracted 45 bids. This coin has been extensively re-engraved. The detail on Ms. Liberty's eye and hair is re-engraved. I present this as a caution for any beginners out there who happen to have a lot of money to spend. Don't get stuck with something like this. Here is Ms. Liberty with an extensive facelift. I fiddled with the photo to make the scratch work more obvious. Here is a genuine example that has been graded EF-45. The eagle on the work-on piece has more detail now than it did in 1795.
Yes, "tooling" is often the term used for coins that have been messed with in this way. It was often done to large cents in the 19th century. Back then it was considered to be okay in some circles. The collectors of my father's generation graded such coins "Basel State - 1", today known as Poor-1. Sometimes you don't know where the re-engraving leaves off.
Re-engraved details is a more specific kind of tooling, yes. In the case of this poor coin, "Re-Engraved" would probably be put on the label. Here's the difference per the NGC glossary: TOOLED - Refers to either the smoothing of a coin’s fields to remove scratches, corrosion and other forms of damage or to the restoration of lost details through use of a graver or knife. RE-ENGRAVED (OBV) - When the obverse of a coin that has had worn or damaged details replaced through the use of engraving or chasing. I more commonly see "tooled" when there has been a spot removal, corrosion removal, or some sort of smoothing of the fields. So, re-engraved is tooled, but tooled encompasses more sorts of alterations.
Someone is not going to be happy when they figure out what they bought. Tough lesson at that price level.
There is actually a pretty decent chance that whoever bought it knew what they were buying. It's hard to say what the grade would be, but at the end of the day it is still a 1794 Half Dollar. A problem free VF goes for $9000.
And one in Good-4 is on the Grey Sheet for $2,500. This thing will not sell as a VF to anyone who knows what they are doing. An expert would stay away from the this piece. I won't pay $500 for it because it's an eyesore. In an honest world, the buyer is down about $2,000. In a dishonest world, he'll make a bundle selling it to a fool.
I absolutely agree that it wouldn't sell as a VF - but to get something with good details (even if they are after-market), there is still demand for it. Would I buy it for a decent price? Heck no. But there are some who would look at that and say "That has really good detail, even if its re-engraved. I'll pay for it." I agree they overpaid for it - but it does still have appeal and value to some people. Essentially, it has "apparent" AU details for a VG price.
After looking at that eye, it's a Battle Of The Bands in my head between "King Tut" and "Walk Like an Egyptian"...
