I have been collecting
Probus coins for over 20 years and one of my sub-collections is
his coinage from
Alexandria. I have not added a new coin to this sub-collection for a few years as I seem to be chasing coins that only come onto the market quite rarely and with some, when they do come on the market the feeding frenzy around them makes them to prohibitively expensive for me to get it when it is offered.
All that being said I have just added a coin to this sub-collection.

6.73 gms, 19.37 mm. 0 degrees
This is one of the five (5)
eagle reverse types known for
Probus.
The
type is not
scarce but is apparently not published for this regnal year.
Not eanting to take the appearance of an unpublished regnal year at
face value I have been discussing this coin with someone (I am not sure that I am free to name them here and thus I will not) and the following challenges to this coin have been gone through.
Year 1 coins are in general much scarcer than most later coins due to the short duration of the regnal year. It not not unknown for later coins to be
tooled to make them appear to come from year 1. Cound this be the converse where a year 1 coin has
had the regnal year modified to create an unpublished regnal year.
To challenge this I provided a more detailed image of the year. This allows inspection of the regnal year in more detail. The serifs are clearly visible on the corners of the Delta and there are flowlines in the fields which give the best indication that these areas have not been modified.
The next challenge is more difficult to challenge. The
bust is quite large compared to others in this issue and is more consistent with earlier years. The best way to progress this is to perform a die analysis and find an
obverse die match to as many examples as possible to see what regnal years the
obverse die turns up for. This would then allow some further analysis to occur to answer some questions. During what regnal years were this
obverse die use? Are there other examples of this die in Year 4? If the die is used across regnal years then are there other examples of an
obverse die being used across regnal years for this period?
Thus far I have not made any progress as I have not been able to find any
obverse die matches. I will continue this activity.
As such there is no reason to doubt that it ia what it appears to be, which is an unpublished regnal year for the
type.
Just for comparison here are my examples of Years 1, 2 and 5.
Year 1 is very much like an
Aurelian portrait
Year 2 - (needs a new photo)
Year 5 (also needs a new photo)
