Two Uncleaned Byzantine Desert Patina Follis
An excellect pair of completely uncleaned coins for your desert patina cleaning enjoyment.
Best guess is that these are Justin/Justinian; easy to clean. Keep them soaking in distilled water and clean while wet with a common dental pick; your saliva will work especially well here.
Our best guess is that after your cleaning, each of these issues wil be a VF+ or better condition.
