Title: my growing brockage collection
Post by: Victor on September 17, 2024, 10:55:58 AM

I have a few brockages and though I didn't set out to have a sub collection of them; I guess that I do now  :D

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

Obverse brockage


This Constantine I brockage has a line under the reverse bust. For some obscure reason, somebody did this to the flan before striking; which is why the bust obscures most of it.

Yes, the partial from Aquileia is probably my favorite and also the most expensive...though it was only like $125
