This section covers
"BON"
(Martini Pangerl Collection 42)
"PROB" (countermark Martini Pangerl Collection

"PRO" (countermark Martini Pangerl Collection
48)

"AS" (countermark Martini Pangerl Collection 39)
"S" (countermark Martini Pangerl Collection 4)
"XLII" on a Galba As

These are countermarks giving worn and imitation coins
from the Julio-Claudian period official value, sometimes downgrading them
from e.g Sestertius to a Dupondius, or from a Dupond to an As.
The countermarks could be as early as Claudius, and as
late as Titus, Nerva, or even Trajan

NL (countermark Martini Pangerl Collection 42)

Countermarks downgrading worn or imitation AE coins from
the Julio-Claudian Period
"DV" and punch on obverse of an imitation
(or Gallic) Sestertius of Claudius. "DV" is commonly found in the Pannonian/Moesia
region and downgrades this underweight Sestertius to a DVpondius. (countermarkMartini
Pangerl Collection 85)

more "DV" countermarks on Claudius Sesterti from
Moesia region

"DV DV DV" on a Claudius sestertius
"DV" on an imitation coin of Tiberius, while it
is normally on imitation coins of Claudius
Halved coin with "DV" countermark

"DV" on a brokage coin

more "DV" countermarks on Claudius sesterti
"DVP" Similiar countermarks
are found in the Rhine region, but as "DVP & punch" on the reverse
of Sesterti (countermark Martini Pangerl Collection
46)
and as "AS" & punch" on Dupondii downgrading
these to an As. (countermark Martini Pangerl Collection
39)
The "S" punch on the coin below likely downgrades
this worn As to a Semis (countermark Martini Pangerl
Collection 4)
More "S" below, the upper maybe is rather a stylized dolphin ?
"XLII" on a Galba As. After
the Western Empire had collapsed, Germanic kingdoms took its place it Italy
and Northern Africa. The Vandals started minting bronze coins with the
denominations
of 1, 4, 12, 21,
42, and 83 Nummi, and apparently also brought Sesterti
and Dupondi of the first and second centrury AD back into circulation marking
their value in Nummi. Such marks are thus known on Sesterti as 83 Nummi
(LXXXIII) and on Dupondi as 42 Nummi (XLII). Most interesting in that they
prove coins still being in (or having been brought back into) circulation
some 500 years after their initial issue. Unpublished is the below example
of a IIII mark on a Constantine AE likely belonging to this issue also.
Contrary to these Vandalic issues the Ostrogoths
in Italy under Theoderic and his successors seem to have issued bronze
along the Byzantine monetary system with 5 (V), 10 (X), 20 (XX), and 40
(XL) nummi coins, often with the legend ROMA
INVICTA.


actually not a countermark, but cut into the coin
Below countermark "IIII"
on a Constantine II coin, possible Vandalic issue
for 4 Nummi.
