Some observations and comments pre-cleaning:
Coin #1: 26.5mm, 7.84g.Details are completely obscured, but this is a big coin, so I have high hopes that enough crust can be removed for
identification.
Coin #2: 26mm, 3.63g.Lots of green crusty bits on this one. I'm a
bit skeptical that I'll see much more than what is already visible. Which isn't much.
Coin #3: 20.5mm, 3.56g.Details are very obscured on the
reverse, but the
obverse shows some promise for at least a general
identification.
Coin #4: 24.5mm (widest), 3.42g.I THINK I recognize a
panther motif on the
reverse, and what I can read of the
reverse legend suggests
LIBERO P CONS AVG. The
obverse portrait suggests
Gallienus.
Coin #5: 21mm, 2.86g.I can just make out "IOV" and "VATORI" on the
reverse, which leads me to believe the
reverse legend is
IOVI CONSERVATORI, and the figure is
Jupiter. I can just make out "Licin" on the
obverse, which suggests Licinius.
Coin #6: 22mm, 1.71g.I can make out two figures clasping
hands on the
reverse, but can't identify the
face on the
obverse or any of the legends. This one seems to have a "desert
patina", I'm assuming that I should be trying to preserve this.
Coin #7: 16mm, 3.00g.I see a figure and what appears to be a
standard on the
reverse, but can't identify the
face on the
obverse or any of the legends.
Tonight I'll do the initial scrub with a toothbrush, soap and water and see what happens. The distilled water soak stands by...
