Are the brockage roman coins rare?
« on: August 20, 2016, 08:35:12 am »
Hallo,
are the brockage roman coins rare?
The one i have, is from SIS mint with the two captives: [LINK REMOVED BY ADMIN, SEE IMAGE IN THIRD POST]
Only the reverse is clear (extremely fine) and it is repeated as brockage on the obverse side.
Do you thing that such coins are rare and collectable?

Thank you

Brockages of the rev. are very rare. I have only examples with the obv. Can you show us your coin here?

Best regards

Thank you Jochen!
Here is a photo of this coin.
In reality the details of the coin are sharper and there is a nice gray patina like silver tonus.
The photo is not the best and cannot give the real shadows and the incuses of the brockage-reverse.

Wow, that is nice and clear.

Congrats on a cool find!

I've read that reverse brockage become less rare in late imperial period, but I can't recall seeing one posted on this forum since I joined.

They are not terribly rare from the Gallic Empire period.  A lot depends on the style dies used in any period.  Does anyone have a Gallic  obverse brockage

Not Gallic but the same era. Here's a fun Claudius II obverse brockage. Sorry for the distracting background  :tongue:

Edit: actually this is a clashed die strike maybe?

A clashed die, not  a brockage!

Tetricus I, AD 271-274
AE, Antoninian, 3.1g, 16.6mm
obv. [IMP ... TETRICVS AVG]
        Bust, draped (and cuirassed?), radiate, r.
rev. VICTOR - I - A AVG
       Victoria with wreath and palm advancing l.
ref. RIC V/1, 140-142

The lack of evident silvering and the overall size and style point to this being an issue of Tetricus. Because of technical reasons reverse brockages are much less common than obverse ones. But John P. Goddard in Met. Num. Vol.3, p.71ff. states: In the coinage of the Gallic Empire we find that rev. brockages occur equally frequent like obv. brockages in contrast to other periods. That leads to the suggestion that dies with obv. motives and with rev. motives have had the same probability to become the lower die. Then it should occur that a coin get two obv. sides or two rev. sides by chance. And indeed, in the Appleshaw hoard a coin with two obverses was found. 

Best regards
