Errors?
« on: November 10, 2012, 11:55:58 PM »
Is anyone else here interested in Late Roman Error coins?

This Magnentius is a flip over double strike (not very unusual in late Romans) but the first strike was a brockage so this coin shows three strikes of the reverse (one incuse) and only one of the obverse.  It started as a Magnentius RIC 138 page 187, I believe?

I find some errors interesting, like overstrikes. I had one brockage, but I sold it. My favorite errors are not striking errors though, but mistakes the engravers made with the die like spelling, wrong mintmarks or errant fieldmarks.

What do you see here?  Rotating the image make it a little easier to diagnose.   My main question is what was the mint of the top strike?  The undertype is clearly Aquileia.

I am not sure, I stared at it until I was cross-eyed! The obverse legend looks like it should be DN CONSTANTIVS IVN NOB C with an A behind the bust. The reverse looks like it has a gamma in the left field, but I can't really make out much in the exergue.

Very special and interesting errors. I do like errors too and when they are combined with a commemorative Constantinopolis coin.....

This one (probably a GE) seems to be a common brockage, but there is something more that I can't identify, a re-strike?

My best guess is an undertype of RIC 107 Aquileia overstruck with RIC 343 or 345 Siscia.  That last mint is mostly a guess but fits the II in the reverse field.  I may be imagining a shadow of an S in SIS at the bottom almost aligned with the S from the obverse legend that fell at that same region.  I am not 100% clear on ID of Siscia Gallus portraits but believe this is possible here. 

The CII brockage reminds me of my Tetricus (???)which I attributed to the coin falling part way out between two blows of the hammer.  I really do not have a certain answer for how this happened but suspect each coin received more than one blow of the hammer and something like this shows a shift between these sequential hits.

Here is one that is a bit of a mess...it's interesting because it is two different busts.
