Edge - Electrotype (Galvanocopy) Stamped RR (Robert Ready)124 viewsIn the late eighteenth to mid twentieth centuries electrotypes were made as originally officially sanctioned copies of specimens in public collections, including the Ashmolean and the British Museum. They were not meant to deceive, but were to be employed as teaching aids for numismatists who might not be able to see the genuine coins in the collection, and serve as display examples for individuals who wished to be able to have an example of specific coins. The majority of electrotype copies were produced by the British Museum, most under the auspices of Robert Cooper Ready and his sons between 1859 and 1931. A skilled seal maker and modeler, these electrotypes are known by the letters RR stamped on the coin’s edge. They are highly sought-after collectables in their own right. At one point, a large portion of the coin collection was electrotyped, which proved to be widely popular with Museum customers and art enthusiasts. However, later unscrupulous individuals used these electrotypes to deceive the unwary, and the British Museum halted the process. Joe SermariniApr 05, 2019

Edge - Electrotype (Galvanocopy) Ptolemaic Bronze Replica151 viewsPtolemaic Bronze Replica - Electrotype (Galvanocopy)
Ptolemaic bronze coin (AE32, 25.2gm). It is 'light' for its size. Note a little 'bumpiness' of the surface near the face of Zeus. And the 'coppery' color is unusual for a real Ptolemaic bronze - another hint it's not right. Note also the 'dent' at the edge in front of Zeus. Flaws in cast Ptolemaic bronze flans aren't that unusual but this is probably an actual dent of the copper electrotype shell.
Magnification of sections of the edge seam are provided below the obverse and reverse images.Joe SermariniApr 05, 2019

Edge - Electrotype (Galvanocopy) Ptolemaic Bronze Replica138 viewsPtolemaic bronze coin (AE32, 25.2gm). The is an electrotype (assembled from plated 'shell' halves, filled with lead or tin), possibly of a cast. It's unusual in that this 'size' for this type doesn't exist so the original is something of a mystery. And it's highly unusual to find a fake Ptolemaic bronze at all. It was probably an educational or museum study piece not intended to deceive.
Magnification of an area of the seam where separation is notable and there's some gray material between the edges of the seam.Joe SermariniApr 05, 2019

Magnification of edge of the coin showing an apparent seam, but hard to tell because at this point the seam is nearly perfect but there are some file marks. See our additional images of this coin where the seam and the fill material are easily visible. Joe SermariniApr 05, 2019

Edge - GENUINE COIN - Study Image of Edge Crease to Compare With Casting Seams 177 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. Unlike this crease, a seam protrudes. The coin is genuine. Joe SermariniAug 11, 2017

Edge - Sprue and Edge Seam212 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) Joe SermariniAug 11, 2017

Edge - Sharp Edges and Casting Seam122 viewsThe angles between the edge of the coin and the faces of a cast coin may be unusually sharp. On worn coins these edge angles should be more worn than the rest of the coin. Typical casting seam. Joe SermariniAug 11, 2017

Edge - GENUNE COIN - Study Image of a Seam-Like Crease 142 viewsThis denarius of Maximinus I has a deep edge running around the edge of part of the coin. It might look like a seam, however it was caused during the striking of the coin, not a casting process. Fold lines are common on struck coins, however sometimes cracks appear instead. It probably depends on the quality of the metal. Note: The line appears closer to one edge of the coin. In a cast coin, one would normally expect the seam to be in the middle.Joe SermariniAug 11, 2017
