Hi,
Any suggestions for this beat up Postumus? Am I done?
IMP C POSTVMVS PF AVG , (IMP) COS V Victory standing right holding palm and wreath.  Any idea where it was minted?

Maybe boiling in soda solution may help to reduce the red corrosion spots and turn the colour to silver-billon gray.
Try it out but stop immediately if it´s getting worse.

I think this was minted in Cologne, emission 20, 267-8 AD ( rated scarce).

excellent idea! Thanks, I didn't think of boiling it in soda.  Carbonate, bi-carbonate or sesquicarbonate (sound like a bartender)?

There are a few topics on it I am pretty sure they all said that there is no difference between sesqui and bi.

I may be wrong, but I thought that sesquicarbonate was a combonation of carbonate and bi-carbonate...no matter, when doing bronze disease soaks I use sesquicarbonate and when just doing cleaning soaks I use carbonate (washing soda -Arm and Hammer to be exact).
