Hello all,new to the forum but not to collecting coins. I am new to the world of ancients though, so I'm sure I'll be posting regularly.

Picked up a lot of crusties after doing some research and deciding that's the way I wanted to go. Like the discovery aspect, and being able to learn about the coins as they slowly become clearer. Wanted to start with Greeks, but Romans were far cheaper.

All the coins in the lot were dirt clods with a faint outline of a head on 3-4 of them. The photos show the coins after about a week in and out of oil and hydrogen peroxide. Out of all the coins, one seems to be "done" to my eyes as it doesn't bubble anymore in the peroxide and no dirt is removed through scrubbing after the oil soak. All the rest still have dirt coming away after every scrubbing.

Curious about the condition on that one; it's the top coin by itself in the photo. The surface is rough, but nothing else will pick away (toothpicks) and it scrubs clean. Think I had an old penny with a similar "flakey" surface, but couldn't find it to compare.

Wondering what causes this or if it's common in old Roman coins of this nature?

I also assume the issues on the 2nd and 3rd coins (second row) are fairly common as well. One appears to have extra metal around the nose while the other... well, I don't know what happened to his face.

- tacked another larger photo below, been a while since I've posted coin photos

It all depends upon what the coin has been sitting in for the last 1700 years or so. There are all sorts of surfaces that you are left with. You don't want to remove the patina and get down to bare metal, no matter what the surface looks like.

If you are new to cleaning ancients, they are unlike modern or medieval. Personally I prefer distilled water to olive oil. Others prefer olive oil, it is personal preference. I wouldn't use hydrogen peroxide though. There are no shortcuts and coins can take from hours to many months to clean. Patience is your friend here.

Sorry! Welcome to the community :)

Thanks for the response and the welcome.

Actually got another batch in this afternoon, so I have something else to compare them to now in regards to the composition and surfaces. Definitely a learning process.

i think the bottom two may clean up a bit more, like that very dark stuff over the bust on the lower right coin and the brown stuff on both lower coins. a week in olive oil isn't much time, i'd keep going.

I agree both coins on the bottom row will clean more, but I think the first one is possibly a die break? Near the nose there's extra metal, got it a little cleaner last night and compared it to a similar old roman coin with a "nose" issue.

I'm clueless as to what happened with the second one though. The photo isn't great, so it looks quite different up close. Almost looks like the face is melted in that area, and I'm pretty sure it isn't something that will pick away. Seems to be part of the coin.
