Evidence of Casting - Wavy Fields1517 viewsMacedonian Kingdom, Alexander III, the Great, 336-323 BC, 4dr, Messembria
AR tetradrachm [Toronto]

At higher resolution, one can see clear casting pits. There is evidence that the obverse has been tooled to remove casting flaws. The devices and lettering are soft. This Toronto Group forgery was offered under the name "Oceans purity".
Joe Sermarini: The rises and dips in the fields are also a sign of casting. Look between Zeus' head and the eagle.

Evidence of Casting - Identical Flan Shape (Edges)2131 viewsEvidence of Casting - Identical Coins. For all but the most expensive fakes a forger will want to sell more than one copy. Completely identical edges are impossible in two different genuine struck ancient coins. These two coins must therefore be cast modern fakes. (They also have other characteristics of cast coins.)Joe Sermarini

Evidence of Casting - Absence of Metal678 viewsThis is an unsuccessful cast and an extreme example of the absence of metal. Most forgers would just remelt a fake this bad.
The hole is not drilled or punched through the coin. This is a flawed cast where not enough metal was poured to fill the mold.
Caution, there are some genuine coins struck on flawed incomplete flan with similar casting flaws. This mint error is, however, uncommon and mostly seen only with Judean prutot. Genuine coins are struck and the details of the types will not have a cast appearance.Ilya Prokopov

Evidence of Casting - A Clear Example of Soapy Soft Details2406 viewsObvious cast for study. Syracuse tetradrachm.
Imagine a fancy bar of soap made as sort of an over-sized coin replica. (Fancy hand soap for the guest bathroom!). After people use the soap a dozen times the sharp details are lost, not just on the high points but everywhere. Coins do not wear like a bar of soap, they wear on the high points while protected areas stay sharp. This coin perfectly demonstrates the "soapy" look.

Evidence of Casting - GENUINE COIN - Study Image of Edge Crease to Compare With Casting Seams3083 viewsSometimes when a coin is struck the metal on the edge folds or forms a crease. This picture shows a normal edge fold or crease, which looks a bit different from a casting seam. The coin is genuine.

Evidence of Casting - Low Weight1986 viewsSyracuse, silver dekadrachm, Dewing 898ff. esnible noted:
This is a cast fake.
First, the weight [34 grams] is too low for the coin to be genuine.
Second, casts have less detail that struck coins in similar grade. Compare to this genuine example: [ http://www.coinarchives.com/a/lotviewer.php?LotID=2860&AucID=6&Lot=109 ]. Note how this coin has less detail, especially in the crevasses that are not worn.
Third, it looks like there are similar-sized bubbles throughout the coin. Although 'bubbles' can also indicate corrosion, it should be a warning sign if they are evenly distributed throughout the coin.

Evidence of Casting - Sprue and Edge Seam4649 viewsIt was described on line as a Septimius Severus, silver drachm. The original is one of the die pairs listed AMNG I, 1, no. 1354. It is a silver simple 2-mold cast of an AE 18-19 of Nicopolis ad Istrum. This coin is reported in Roman Provincial category. The face of Apollo on the reverse was "improved", there is a seam between the two halves, and evidently a sprue, as well. Contributed by P.L. Patricia Lawrence (slokind)

Evidence of Casting - An Example with Obvious Casting Flaws4226 viewsClick to see a larger image of an extreme example to help new collectors understand what soft details, etc. mean. All features are rounded. Nothing sharp. Everything blends into fields without distinct edges. It is fairly obvious the pits are not corrosion, but from air bubbles in the liquid metal. Even though the edge has been filed, there is still a trace of the seam. Posted on the boards by peterhill.

Evidence of Casting - Excess Metal547 viewsHere we see excess of a metal from poor packaging for casting. This is an extreme example that most forgers would just remelt. Similar defects may be found on a genuine coins resulting from a broken die, but a broken die flaw will not have the same soft rounded appearance.Ilya Prokopov
