Several years ago I acquired an interesting bronze coin of Gordian III from Antioch - Pisidia, pictured below. Antioch-Pisidia. Gordian III, AD 238-244. AE 34 mm, 26.43 gm, 6 h. SNG France 1211. Al Kowsky Collection. While browsing through the latest offerings from Roma E-Sale 95 I spotted a double-die match for the coin in my collection. The Roma example appears to be a later strike from dies in a more degraded condition. Antioch-Pisidia. Gordian III, AD 238-244. AE 34 mm, 29.86 gm, 7 h. RPC VII.2 Online Unassigned ID 3423 (temporary). Roma E-Sale 95, lot 725.

The image of a double strike is from two striking's with a shift in the planchet, these coins are both struck from the same dies.
