Not sure if I should post this here, start a new thread, or search other threads and post there. is the scratching on this coin from a bad job of cleaning or expected wear given the age of the coin?

Looks like an overcleaning, yes. It's normal for ancient coins to be cleaned (they tend to come out of the ground pretty dirty...), but this one does look like it's been just straight-up whizzed.

Quote: Not sure if I should post this here, start a new thread, or search other threads and post there. Best practice is to start a new thread for each new coin, so I've split out your post plus @j1m's reply into this thread. Also, this looks like a Tet from Athens, but please correct me if I've mis-identified the coin. Thx. Added: As to your question, @j1m is 100% correct. This amount of surface modification though borders on field smoothing with an intent to bring up features that have long worn away. I have tons of coins that have been whizzed in my collection as they came to me from my father and his father, but I generally wouldn't seek out a coin with this problem.

Spence, Thanks for moving the topic and info! Yes, it's an Athena Owl tetradrachm I think I saw on ebay. So this level of cleaning would decrease a coin's value, correct?

Yes, but it isn't because it is cleaned vs. uncleaned but rather that someone has unethically tried to move metal around to add back details that time and use have worn away. At 2000+/- years old, all coins have been cleaned to some extent.

For many ancient coins, there is a fine line between "cleaning" - the removal of encrusted debris - and "tooling", the re-engraving of lost details onto a worn or corroded coin.
On some ancient silver coins, "horn silver" or silver chloride can form. This can only be removed by either harsh chemicals or by physically hacking at it with diamond-dusted dental tools. I suspect that is what has happened here. The question then becomes, has this crossed the line from "cleaning" to "tooling". I am concerned it has in fact crossed that line.

I see no attempt at tooling...merely what looks like aggressive cleaning. A full picture would also be more helpful.

Hmm in addition to potential tooling around the feet, I'm also really not liking that porosity on the obv. You don't have a shot of the edge do you?

I'll try to get some edge photos. What does "porosity" mean as it relates to coins. Is it the holes in the coin?

Porosity literally means porous, or full of tiny holes. Cast coin often are porous from gas bubbles in the finished product. Spence, if this coin is cast, whoever worked it over with the wire brush probably removed any seam or sprue material.

I found another coin, but in the description of the coin the dealer (USA) says, "Obverse has unpleasant encrustation. EF." To my newbie, untrained, uneducated eye it looks great! What am I missing?

Quote: unpleasant encrustation Perhaps there is horn silver in front of Athena's face? Hard to tell from the seller's pics though.
