I have a liking for Mars types and have bought many MARTI CONSERVATORI coins over the years, primarily Constantine the Great, occasionally Licinius but this is the first time that I have stumbled across one produced for Maximinus II Daia. I might have a go at removing some of the red and white adhesions but the thought of damaging the coin scares me to death. Follis Obv:– MAXIMINVS P F AVG, Laureate head right Rev:– MARTI CONSERVATORI, Mars standing right resting on shield and spear Minted in Ticinum (//PT), A.D. 312-313 Reference(s) – RIC VI Ticinum 123a (S) 5.03gms. 22.34mm. 0 degrees Does anyone else have any M II D - MARTI CONSERVATORI coins to share.... or just M II D in general, but Mars types of M II D in particular.....
Nice coin @maridvnvm - it would be great to be able to remove the encrustations but a bit challenging without wrecking the coin I guess.
In my experience sodium thiosulfate is pretty effective at removing iron oxides without damage to the coin
Hot wheels, have you tried sodium thiosulphate on copper/ bronze coins? I have tried it on silver, but not copper.
I will just leave the coin like it is, is beautifully toned. If you mechanically remove the white deposits you will have red spots in return(first M.. obverse legend)
I have not, only on silver. Worked wonderfully to remove the oxides that hydroxide would not remove. I will probably toss a junkeR bronze into thiosulfate Just to see what impacts it has
