Curious, could you trust the weight reading with that much crud on it?
Has anyone weighed their encrusted coins before and after cleaning to see how much weight it added? Obviously the responses will never be uniform, but I wonder if there is a range that can be deduced?
In hand it did not look much better. When I used a flashlight at an angle, some features were visible.
This coin was clean from the seller. I did not try cleaning it.
Your coin looks like it could use a good distilled water and / or olive oil soak followed by gentle brushing with a soft tooth brush.
Measure and weigh the coin now. You can always weigh it again.
Looks like Flintstones money
To me it resembles an Alexandrian Tetradrachm of the 3rd century, in this case the weight would be important.
It would also help to post size and thickness ( thin or fat )
It's quite possible you would wind up with a more-or-less featureless disc - or just debris in the bottom of the tank - if you were to do electrolysis.
One plus for electrolysis, however, is that it's pretty good for removing superficial active BD - if BD has established itself in the core of the coin, there's little chance you will ever be able to salvage "a coin" out of this lump at all.
Some of them are simply too far gone - you just can't reasonably ID them. Deep forensic study might shed some light on its origin, but I know folks who save those "hopeless" pieces and for a goof scatter or bury them shallowly in public places or elsewhere their presence might confound some future archeologist. Not too sure about the overall propriety of that, but it is something you could do other than flipping it directly into the bin.
I do applaud you for trying - many impatient or profit-centered folks give up on much better preserved pieces than this. Working with barely identifiable coins is a great way to build your identification "chops", although it can be very slow and frustrating going until you clear the first steep learning curve. Don't let this discourage you too much.
As for "cleaning", go ahead and try if you're so inclined. You're not going to be able to cause any real "damage" to a valuable piece here. By definition, it's unlikely to be rare, and it's already probably 99% dead.
Honestly no clue where. Hand me down.
This Diocletian tet is fairly representative of what they look like in a little better condition. The weight of yours at 10 grams is a bit high, but these sometimes were that heavy - this Diocletian is 9+ grams.
This is one on which the regnal year is spelled-out rather than represented with the modified Egyptian heiroglyphic for year => "L" and a Greek numeral or two.
