This is a great error variety that has the NB Fluer de Lis stamped in the wrong quadrant then corrected with the proper Austria bar.

A horribly tooled coin.

KA•A• = officina 1 — officina H (8) not possible at Serdica.

Serdica, RIC 888 variant = Cohen 927 (not listed for officina) p. 115. // KA•A•

RIC 880 = Cohen 915 has a different reverse type: Emperor galloping right, spearing enemy whose shield lies beneath horse.

Julian II

Die Legende in der Beschreibung stimmt nicht mit der Legende auf der abgebildeten Münze überein (The legend in the description does not match the legend on the coin.) Die Legende lautet (It should read): Rs.: C PLOTIVS RVFVS IIIVIR A A A F F und Vs.: TRIBVNIC POTEST CAESAR AVGVSTVS

eher KdKahle

Charlemagne ou Charles le Chauve ist nicht mehr erforderlich, die Münzen lassen sich anhand der R zuordnen, pn

KdE hat schwerere Denare geprägt, 1.04 Gramm ist eine viel spätere Prägung, pn

Monogramm R und FR zeigen eindeutig KdKahle an.

Anhand der R eindeutig KdK zuzuordnen. pn

Look at this alongside Lot 3998 and 3999 - there was a 3-way mixup w/the photos. The photo shown with this lot is indeed a 1619 - "(16)19" - and is correct for Lot 3998, a Mexico 1619/8 2R. Note also that in reference to your recent comment on that 8R - that is indeed a proper rendering of "9" as seen on Mexico 1619 pieces.

The 1655 2R is shown erroneously with Lot 3999.

Lastly, the pic shown w/Lot 3998 would appear to be what they are calling "1629" in Lot 3999. While you can see how that could possibly be construed as "629", I don't see that as correct (I think that assayer mark is "F", and the style elements seem to back that up).

Bummer. I wish I could see the other coin in this lot. I just see what looks to me like a bold 19. If someone has the 55 would you contact the Spanish Colonial Numismatic Society? Thanks!

This is RIC 157, p. 35, MPR 399, p. 192. The mark is R ჲ Ϛ (R wreath digamma).

This is a forgery from modern dies, style, surfaces and lettering are wrong.

This is a forgery from modern dies, style, surfaces and lettering are wrong.

This is a coin of Rome, and the mark is Rε. The epsilon can be seen between the right wheel and the terminal O of SOLI INVICTO. This is a variant of RIC 204 (not listed with this bust), p. 39.

See "The Gloucester Hoard and other coin hoards of the Britannic Empire" Plate 36, 1054.

This is a coin of Siscia, RIC 776, p. 101. Cf. Alföldi 73/49.

Wrong obverse for this reverse, photo of reverse has been mixed up with: https://www.acsearch.info/search.html?id=1430104

This is one of the many variants of RIC 779, p. 102. A coin of Siscia.

Since this is marked RB, rather than with any marks of Cyzicus, this is RIC 204, p. 39. A coin of Rome.

RIC 71

This is a RIC 723 variant, p. 94. RIC doesn't list it from officina Q but titulature and legend combinations are valid for 723. Cf. Alföldi 53, 51-55.

This is RIC 650, p. 87, as obverse titulature is the longer IMP C M AVR PROBVS P F AVG.
