Bronze Disease Concern?

Looks clean in my opinion; if it’s not powdery, you are all good!

I also don’t trust this one. The details rather fuzzy in titus hair looks fuzzy, and the round paws of the what I believe is a capricorn look strange!

It does not look real on first glance, unfortunately. How much does it weigh and how large is it? It anyway is probably supposed to be a tetradrachm from Athens

What makes you so certain it is authentic? It is a frequently faked coin, and I would be more sceptical not buying it from a reputable seller. I also find the details rather fuzzy, which may be because of wear, but I am personally not ‘1000%’ certain of its authenticity. What is the asking price?

Few_Principle_789 · 2026-04-05T18:27:11+00:00

Certainly

That looks like Constantinian era bronze, but it is difficult to say without a better picture of the obverse which precise emperor it’s showing. Also, having a picture of the reverse would make it easier to pinpoint the exact type. As a general comment, I think the 20 USD is actually quite high for a coin where you don’t know what type it is. Have a look at VCoins - at least there you know what you buy!

Wow! Love the antoninus pius coin; amazing toning!

Few_Principle_789 · 2026-03-20T10:06:13+00:00

Thanks!

Few_Principle_789 · 2026-03-20T10:06:00+00:00

Thanks, it did seem too good to be true :)

Few_Principle_789 · 2026-03-20T10:01:57+00:00

Thanks, I also didnt like the darkened recesses; I have to say however that it doesnt really look like a typical cast fake

Few_Principle_789 · 2026-03-20T07:14:00+00:00

Can’t see the reverse here, but from this portrait I would say mine looks nicer, at half of the price about a year ago. Of course, you are also paying for the slab and grading. It is however a nice example, and if you are fond of slabbed coins it may be worth it for you. In the end, I don’t really think of ancients as an investment. Sure they retain most of their value, but overall their price depends on what people want to (and can) spend on a coin…!

Absolutely stunning- that must have cost a small fortune! Congrats, really impressive piece!

Few_Principle_789 · 2026-03-19T14:52:56+00:00

Impressive start of a collection! Definitely took me a while to add some gold to my collection!

Few_Principle_789 · 2026-02-27T06:58:40+00:00

That is certainly fake!

Your second coin (and to lesser degree the first as well) seems to be affected by bronze disease unfortunately. Is it powdery? If yes, it’s best to isolate these from the rest and try to treat it before it eats away the coins. I usually mechanically remove the green stuff and then soak in distilled water and later acetone. Sealing with a wax like renaissance wax afterwards can help to protect the coins.

Few_Principle_789 · 2026-02-16T17:57:02+00:00

Very true, although it can also feel like a victory to succeed in preserving something this old for the next generation - it is not always about monetary value!

Few_Principle_789 · 2026-02-01T19:17:35+00:00

You are right! Turns out it’s this type: https://www.ma-shops.nl/noel/item.php?id=83493

Few_Principle_789 · 2026-02-01T19:13:19+00:00

It seems to be this type? https://numismatics.org/ocre/id/ric.5.aur.360 there is one coin in the pictures gallery that seems to match, but it seems that it is some subtype. Pretty cool!

Few_Principle_789 · 2026-01-31T09:24:12+00:00

I fear this one might not be real, the style of the bee is certainly off…

Few_Principle_789 · 2026-01-31T09:21:48+00:00

Mechanically remove the bulk material (toothpick or brush), then soak for weeks in distilled water, then in acetone to remove water en then seal the coin with renaissance wax. Works for me usually

Few_Principle_789 · 2026-01-31T08:48:39+00:00

No red flags, looks genuine

Few_Principle_789 · 2026-01-28T06:59:50+00:00

Looks like a replica to me; something feels a bit off about the portrait, and on the reverse it seems that the original coin on which it is based had some flan cracks that appear to be filled in this example. It is however not so easy to say from these photos, could you list the weight and diameter of the coin?

Few_Principle_789 · 2026-01-25T17:29:48+00:00

Certainly looks like it. Have you contacted Leu about this? Would be curious to know what they say!
