Bimetallic medallion cast in one metal723 viewsCurtis Clay noted: It is a cast. Note the circular line inside the edge on both sides. On the original, that was the dividing line between a red copper center and a brass edge or vice versa, a bimetallic medallion which was apparently considered fancier because of the differing colors of the metals.
On this medallion we can see in the image that the edge and the center are the same yellowish metal. A unimetal bimetallic medallion, because it is a modern cast not an original! Fortunately you cannot cast center and rim in two different metals so as to make your fake more deceptive!

Lead cast silver washed Dirham1301 viewsCast lead coin that has been silver washed - coin is very heavy and the high points are blurred or soft - silver wash is chipping off all in all a fairly poor forgery.
The coin was purchased on eBay as part of a general collection of coins and the seller was not aware that it was a forgery.

Pertinax denarius - silver cast from a genuine aureus822 viewsCurtis Clay noted on the boards: "This "denarius" is condemned as a cast not only by its appearance, but by the fact that it is struck from aureus not denarius dies. Its obverse die is the same as that of the aureus M&M 66, 1984, 673 in our photofile. But by this time aureus dies had become larger and finer than denarius dies. The two denominations had their own dies and no longer shared them, as they generally had done up until the early years of Domitian's reign. The eBay coin in question is a modern silver cast of an authentic Pertinax aureus."

Silver Plate vs. Silvering1601 viewsThe top coin is a modern silver plated reproduction. The original type was not, however, silver-plated. It was "silvered." The bottom coin is a genuine silvered antoninianus of Probus. If you have never seen a "silvered" coin in hand it may be difficult to know the difference. But once you have seen a few genuine silvered coins, the difference is clear. Replicating the "silvering" of ancient coins is apparently not an easy task for makers of replicas or forgeries.
