I wanted to share the following coins. Not only are they nice examples of post abdication folles of Diocletian and Maximianus Herculius but also have some additional interest to numismatists.
Diocletian as Senior Augustus Follis, (first coin)
Obv:-- D N DIOCLETIANO FELICISSIMO SEN AVG, laureate bust right in imperial mantle, olive branch in right hand, mappa in left
Rev:-- PROVIDENTIA DEORVM QVIES AVGG, Providentia standing right, extending right hand to Quies standing left, branch upward in right hand, vertical sceptre in left
Minted in Cyzicus (not Trier) ( S F / KS //PTR)
Reference:-- RIC VI Trier 677a (Rated Rare)

I also have a link to a larger image of the coin in case anyone is interested:-
http://www.forumancientcoins.com/ga...41br_img.jpgIt is attributed by RIC to Trier (Treveri), but a comparison of portrait styles and an examination of follis hoards reveals that this issue was not struck in Trier but in Cyzicus.
It would appear that the prototypes for this type were made in Trier and then exported to the other mints for their implementation of the type. It would appear that when the engravers at Cyzicus made their first copies they copied everything, including the PTR mintmark and then added their own mintmark in the centre field. Someone must have realised their mistake and the issue is relatively short-lived and is followed by an issue without the PTR in exe and the Cyzicus mintmark moved to the exe. This is illustrated in the second coin attached:-
Maximianus Herculius as Senior Augustus Follis, (second coin)
Obv:-- D N MAXIMIANO FELICISSIMO SEN AVG, laureate bust right in imperial mantle, olive branch in right hand, mappa in left
Rev:-- PROVIDENTIA DEORVM QVIES AVGG, Providentia standing right, extending right hand to Quies standing left, branch upward in right hand, vertical sceptre in left
Minted in Cyzicus (S F // KD). A.D. 305-306
Reference:- RIC VI Cyzicus 23b (Scarce)

Again a link to a larger image:-
