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.

Cast known from clones. Most cast coins will not have this sort of rough surface and similar surfaces can also result from corrosion. Joe Sermarini

Evidence of Casting - Metal Filled Crack, Raised Edge on Rim, Soapy254 viewsThe metal filled crack is a 100% certain indicator of a cast fake and makes this an obvious fake to even moderately experienced collectors. The raised rims on the obverse and reverse are sometimes found on genuine coins due to edge bumps, but are also common on cast fakes. The details are a little soapy, another indicator of a cast fake.

Evidence of Casting - Missing Details That Were Off-Flan on the Coin Used to Make the Mold3005 viewsThis is a pressure cast forgery made with molds created using the lost wax method. First a mold is made using a genuine coin. Copies are made in wax using that mold. The advantage of making wax copies is that the edge rim is easily removed from wax. In addition, small changes can be carved in the wax and new flan edges and shapes can be created for each copy. These wax coins are then used to make new molds each of which is unique and does not have a seam. Instead of splitting the mold creating a seam, the wax coin is melted and burned out of the mold. The mold must still have a sprue (and usually two per coin). The casting is then done in a centrifuge to eliminate most of the air bubbles and other evidence of casting. This pressure casting is not completely effective because under a microscope the evidence of casting is still visible. This coin has an obvious sign. The crest of Athena's helmet was off the flan on the original genuine coin used to create the first mold and wax copies. The forgers made the flan of this fake a little larger than the original in the area above the helmet from 9:00 to 12:00, but the forgers did not recognize this area of the flan should not be featureless and flat. It should have the more of the helmet's crest, which is visible only from 8:00 to 9:00.

Evidence of Casting - Polishing666 viewsThe coin is a cast from a genuine coin, so called "Thasian type". The obverse was finished by hand - traces from casting were polished with hand instruments. The same process has been started on the reverse but was not completed.
Traces can be seen on the obverse around the Herakles I lion skin - there was some polishing of casting knots.
