4 Ancient Coins Age And Value

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:

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

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:

There is NO gold in the three roman provincial coins. Not 40%, not 20% but none. Do not buy these thinking there is any gold in them. There is NO gold .

They are three rather poor quality roman provincial of what looks like Gordian and Gordian and Tranquillina - as someone said £10 each for approx value.
