you can use a test kit with a stone to test for various types of gold or silver. Some one else at CCF here will help you id the coin.

I can tell you for certain that none of them are gold. The heavy ones are most like Sestertius which are heavy and brass (hence the idea of gold)

Well hang on - Byzantine silver is rare and expensive! Thats probably worth quite a lot.

The silver coin is from Venice one of the Doges. I see if I can find who it is. The others are all Roman provincial coins. When I get back home later I'll see if I can pin them down.

another way to test for silver is putting it on a cube of ice... if it is silver it will melt into the ice because silver remains a constant temp.

Yes Echizento, the coins are real, I was just told that they are gold again!(tested with some toolkit). I don't have the coins near me so I can't measure the weight. but for the first image I can tell the weight was above 20 grams, I searched a lot but was unable to find more info.

There is little question as to their authenticity. They look fine. However, they are most certainly NOT gold. Gold is an extremely stable element and really only reacts to one thing. That is a mixture of nitric and hydrochloric acid (Aqua Regia) therefore there would not be any "Patina" on a gold coin like you see in the pictures here. If these were gold coins, they would look like this:  Edited by MartiVltori

The only coin I can't vouch for is the silver Byzantine. The first three are Roman era Greek provincial bronze/brass (orichalcum) coins most likely quite common and in rough shape. probably worth about 10 dollars each.
If the silver byzantine is authentic is is worth substantially more.

I did say the silver one was from Venice and the others were Roman Provincials. There are no gold coins there.

Echizento, the quote was from the OP grunge. Not you. Grunge was implying they were gold.

The silver coin is from Venice and badly clipped. The only significant difference between issues of Venice over hundreds of years is not the design, which remains constant, but the name of the ruling Doge, which is around the edge. When that is clipped and therefore almost illegible, the value of the coin is very much reduced, and Venetian coins are not that valuable to begin with. As with everything under the sun, there is a relevant website: http://www.venetiancoins.com/ |
