These are both common coins, but more interesting because of their flans. This Tribute Penny seems to be an over-strike, particularly visible on the obverse behind the bust. And this is a Ae3 of Constantine III from Trier that seems to have been a brockage on the reverse, then corrected. The ghostly image of the bust can clearly be made out.
http://www.forumancientcoins.com/dougsmith/brock.html for 15 years I maintained there was no such thing as a brockage that was 'corrected' by restriking and I even had a page on the matter where I shouted my opinion. Then a coin found me that I believe is a restruck/overstruck brockage so I had to modify the page. There is no doubt that the coin here is an ordinary die clash. It is also Constantine I not III.
interesting...i'm glad we can post things on here as such and allow others to ring in their opinions and expertise. it makes us all wiser i think.
I think this one is an overstrike on a denarius of Vespasian Titus Denarius. 79 AD. IMP T CAESAR VESPASIANVS AVG, laureate head right / CERES AVGVST, Ceres standing left, holding grain ears with poppy and sceptre. RSC 31a RIC 3 Sear 2504
