I enjoy error coins and have a small collection of brockages. A brockage occurs when the coin gets stuck to the die and the next strike produces a mirror image on one side of the planchet. These are fairly common; though reverse brockages are rarer than obverse, because the mint worker could more easily see if the planchet was stuck to the obverse die. this is a reverse brockage for Gallienus The reverse is AETERNITAS AVG, Saturn with harpa standing right; PXV in exergue. RIC 606 Partial reverse brockage Constantine I A.D. 320 18x19mm 2.3g CONST-[ANTINVS AVG]; helmeted and cuirassed bust right. VIRTVS EXERCIT, [Valor of the army] Standard inscribed VOT/XX with captive seated on ground on either side, S-F across fields. in ex.

For some obscure reason, somebody did this to the flan before striking; which is why the bust obscures most of it. 21mm 2.9g IMP CONSTANTINVS P F AVG Constantine I 20x21 3.3g IOVI CONSERVATORI Siscia obverse brockage Constantine I 19x20 3.0 SOLI INVICTO COMITI Rome Obverse brockage Constantinopolis brockage from Trier 15mm 1.8g Ex 1989 Nether Compton (Dorset) Hoard
Those are cool. So I assume those were just tossed in the pile as if they were struck correctly? Instead of pulling them and re-melting into new flans.
