I ran across an interesting example of a very rare coin that apparently underwent a conservation process, only for the coin to subsequently sell for a considerable loss.

The coin in question is a Tetricus (271-274) Aureus with IOVI CONSERVATORI reverse. I could only find a single example of this coin on acsearch, which is which is why I am calling the type very rare. That example sold three times in the last five years.

1. March, 2020 it was in the condition shown below, mounted and had rather deep grafitti obverse.

Copyright Roma Numismatics
Sale price 2400 GBP, equivalent to about $3100

2. February, 2021 in the same condition, it sold for 4250 euro, equivalent to $5100 at Numismatik Naumann. (Maybe that first buyer played a "pandemic bounce" well?)

3. November, 2021, now with the mount removed and the grafitti gone, it sold at Heritage for $2700:

Curious if that's normal (i.e. that conservation yields unpredictable outcomes), or if anyone has other experiences.

The coin looks more presentable restored, so I would assume the coin would have achieved a higher auction realized value. I am unfamiliar with ancients but generally eye appeal heavily impacts the value across coin collecting. Likely this coin was at the wrong place at the wrong time and the auction failed to perform. Auctions can certainly have mixed results, they are always a risk after all!

Ouch to the one who paid a lot of money to have that work done...

It's a bummer it sold for less. Bad luck I guess.

The new buyer got a great deal on it.

I'm tending to think like this too. As mentioned by jacrispies, the eye appeal is undeniably WAY better after the repairs. And given that only one example of this coin was findable on acsearch, I am assuming there are fewer than 10 known specimens, possibly fewer than 5.
The wording in the Heritage auction listing may also have scared off bidders: https://www.acsearch.info/search.html?id=8766262

It is the same, just ruined. Soda blast to rid the scratches, but can still see traces of them.

I'm going have to disagree.

But what do I know.

Pretty sure it's the same based on the unusual planchet shape.

actually thought it was amazing that I couldn't see any traces of the scratches, but my eyes aren;t as good as they used to be.

Curious: that third time, was it sold as a restoration job, with its prior provenance and appearance well-known?

I'm wondering if the reason for the reduced price is that this coin has perhaps crossed the line from "conservation" to "reconstruction", or "tooled".

The coin in its original state had some context: someone in ancient times had turned it into a piece of jewellery. Perhaps less appealing to coin collectors as a "damaged coin", but as a piece of history, quite interesting. Now, that piece of its history has been erased, leaving just a tooled coin.

The term "smoothed" comes to mind.
