This was a budget buy as "Unknown Greek obol 4th century B.C. The (I assume) double strike on the reverse appealed to me Anyone else collect double strikes ?
Double Gorgon heads! Very nice, @eparch Double struck coins are fun to collect. I also collect this type of errors, but mainly modern circulating coins. This type of error coins looks especially cool IMO when they are "aligned" nicely. Here are two examples in my collection. To keep my reply ancient-related, here is my double struck Roman bronze.

Only double struck coin in my collection - 20 Sol uniface klippe from the 1709 siege of Tournai (Spanish Netherlands, now Belgium). The siege started on 27 June, under the leadership of Malborough, with the defense led by the Marquis de Surville. The city itself fell on the 28th of July, but Surville's forces retreated into the citadel, where they held out until 3 September. These 20 Sol klippes were produced from the 13th of July, being made from the Marquis' cut-up silverware.
Many ancients have a bit of doublestriking so to be a good 'error' they need to be a bit more extreme. This very ordinary Constantius II was my first. Rotated double strikes are fun. Flipover double strikes are more fun. One side of this denarius favors Septimius Severus while the other favors Mars. Of all doubles, my favorite is this flipover Magnentius where the first strike was a brockage. The coin has one obverse strike, two normal reverse strikes and one incuse reverse strike. While I do like doubles strikes, I really(!) like overstrikes. That is another thread.
Gallienus is a good reign for these. I have a double and a flip-over double: We used to call these Kevin specials, but I haven't seen mention of Kevin for a while...
