Need Help Iding Trajan Dupondius

Can't see the reverse.
Edit: Oops, now I can.

It is OK now, maybe just very slow to load.
Is there any chance you can make out any of the legend on the reverse?

You can remove ren wax with white spirit, but I don't know whether this would have a detrimental effect on your coin. Perhaps the others may be able to help. Ben is a budding chemist, he might have some ideas. Google throughly before you try.

I believe the reverse is Abundantia seated left, holding a scepter.IMP CAES NERVA TRAIAN AVG GERM PM TR P /COS II DES III PP. RIC II 406

Acetone is the equivalent available to you - we cant get the stuff here. Unfortunately, Renwax has some polymers in it that arent soluble in regular solvents like acetone. Some people are against it because its so hard to remove.

However, chances are that it isn't renwax (its pricey), so id give it an extended acetone soak anyway to try and remove whatever it is. If you're feeling like it, leave it near an open window exposed to the sunlight and the UV will photosynthesise Acetic acid which certainly would remove Renwax, given time. But would also give the coin minor BD, so you'd have to treat for that afterwards. Of course, this could explode a normal jar in hot weather, so you'd have to leave it open, with perhaps a flap of card over the mouth sealed with vaseline, so pressure cannot build up.

The other method you could try is an abrasive, like a brass brush, but this could damage the coin. I might try looking up methods of removal...Ive never had to.
