"Billon" is a vague term. In antiquity, silver was worth on the order of 100 times as much as copper, so even 1% silver makes the intrinsic value...
Here is one way. Three images are in play, the obverse, the reverse, and a blank image. Create a large blank image (maybe just white) to...
Victor, that is a really nice Crispus page with many good examples. If someone wants to see what is possible when collecting Crispus AE3s, that...
I think the OP folles are genuine and without bronze disease. (There are two "Samaria obols" with disease.) Not all green cover eats into the...
I don't think this price will last long. I figure it's a typo: [ATTACH]
Deleted. I misread the image.
I agree with @zumbly and @TJC . It looks like the obverse is silvered but tarnished (toned).
I love the late Roman AE coins from Valentinian and later (AD 364ff). I wrote this site on them: http://augustuscoins.com/ed/ricix/ The coins...
@Jay GT4 , that is a beauty!
Here is a page on those "quarter-follis" coins, issued only at Siscia. http://augustuscoins.com/ed/qf/ They are about 19 mm, much larger than...
Yes, that is from the same series. They are often called "quinarii," but without any evidence that is the right name. I have used that name...
The pieces from Carthage are larger and radiate (not laureate) and of the common "post-reform radiate" denomination which often has CONCORDIA...
Several people have called the OP coins fakes and thrown the quality of the whole collection from which they came in doubt. Make that several plus...
Under the tetrarchy and later there were some rare fractional denominations. This coin of Diocletian is only 14 mm. [ATTACH] Diocletian, AD...
@Carausius , that is an excellent writeup. The second bull and snake coin almost makes the bull look playful (I've seen dogs jump like that a lot)...
Here is a very high-grade denarius: [ATTACH] ex CNA (= CNG) auction V (Dec. 9, 1988), lot 379 with PR $370 + 10% + shipping = over $410 thirty...
I am in the US. On acsearch I see Lanz coins. A search on Numismatik Lanz brings up many items.
I think it is authentic. Wear can't explain the obverse, but a very worn obverse die can. At 3:30 on the OP coin there is the beginning of a die...
If you want to learn more about ancient coins, you might begin here: http://augustuscoins.com/ed/ and there are many places to buy besides eBay,...
The OP coin is extremely well-centered for a tiny 8 mm cutie! It has the noses on the flan and the top of the helmet on the flan. The strike is...
