Missing Material with round edges225 viewsMissing material with very round, polished edges may be an indication of cast. When the metal is filling the mold it does not fill it completely - circled red in the middle. There is a small cast hole is right next to it.

Circular holes from air bubbles from casting.843 viewsPits (holes) from corrosion are often irregular shapes and are often bunched together, pits from casting than from casting are mainly round. More pitting on one side than the other may be an indication of casting since the side that was up will contain more holes (but it isn't unusual for one side to have more pitting from corrosion too).

Identical flan shape with legend recut in mold223 viewsExample of a cast coin which differs to original and other casting twin due to recutting of the mould. In this case identified by a blundered legend.
Identified by FORVM member Din-X with the following observations: 'The flan shape is almost identical but it seems like that some details were wrong recutted into the mould for example N CLAVDIVS CAE[SAR AVG GERMANICVS instead of TI CLAVDIVS CAE[SAR AVG GERMANICVS. First letters on the obverse could be a TI and not a N! So how can a TI can become a N without wrongly recutting in the dies? Tooling means that material is removed to add details = tooling only removes material but for connecting the T with I and make it to a N extra material must have been added. On the right side on the reverse on both the last part of the legend on the right side is missing ([INA CYTHERO CAPITONE), which is on the host/mother due to wear. The edge crack at 12 o´clock obverse and 5 o´ clock on reverse was filled at the cast fake.'peterpil19Dec 23, 2017

Cast known from clones. Most cast coins will not have this sort of rough surface and similar surfaces can also result from corrosion. Joe SermariniAug 16, 2017

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.

GENUINE - Evidence of Casting - Pits Caused By Fire Damage247 viewsWhen an ancient coin has been burned in a fire, the flan may be warped, have lamination defects (flaking surfaces), and will likely have raised bubbles, and unusual pits. Bubbles are created when small pockets of gas within the flan expand due to the heat. If the top of a bubble breaks off it will leave behind a pit.
Fire damage pits do not look like pits from casting bubbles. On this example the lamination defects within the pits are clearly visible. A casting bubble will not look like this. Joe SermariniFeb 28, 2016

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.

Evidence of Casting - Examples of Wax Copies Used to Make Molds384 viewsGroup of mold of wax used in the production of replicas/fakes by Lost-wax casting.
Picture facilitated by Remoneda in the Spanish Forum Omni in May/2010
The wax copy was made from a genuine coin in a mold, probably made with material used by dentists to take molds of teeth. The edge of the wax and other details can be modified to remove evidence of casting, remove flaws on the original coin, sharpen detail and to make each fake coin unique. Another advantage of wax is that a mold can be made without a seam. Instead of removing the seed from the mold by opening two halves, the mold is heated and the melted wax is drained from the mold. The mold is broke to remove the fake coin, which will have no seam.
