Is it at all possible to identify this coin with strange reverse?

The coin weighs 9.35grams and is 29mm in diameter.
It also has this undestructable green encrustation parts and a nice brown patina.
Reverse has this star like thing in the center.

Thanks

I think it's a lost cause, bro.
Sorry.

My God...
Room full of vegetarians. LOL
Pitty about the coin, there looks to be something nice underneath.
Thanks

 

To me it looks as if it's some sort of Greek bronze with a portrait obverse and a winged thunderbolt reverse, like this one:


Here's a link to where I found this:

I have zero expertise in Greek coins, so maybe someone else can help here.

 

I think the "star" might just be cleaning scratches

 

Could be, strangely centered though.

 

Consider the following side-by-side comparisons:

Obverse:



I clearly see similar outlines of the portrait in the original's obverse.

Here's the reverse, with the comparison coin's winged thunderbolt rotated to roughly match the original coin:



Looks somewhat similar to me.

 

Ummm, could be? (it's kinda like seeing shapes in the clouds)

 

Hmm, I thought those lines on the reverse were gouges/incuse. Also, the obverse figure looks male to me, although the contours may have been altered by corrosion.

@Makanudo, are the thunderbolt-like lines gouges or are they in relief?

 

I've been assuming that the obverse lines are in relief but look incuse because the lighting direction is wrong.

If, in fact, they're incuse, then my theory about the reverse is all wrong.

 

Coins are funny sometimes, eh?

 

with enough pareidolia, it could be anything...

 

I cannot give you much answers as to wether those are incuse or relief.
To me, brown stuff that covers most of the coin looks more like brick clay(baked earth) than patina. The lines on the reverse look to be outlines of something beneath..
I understand theres no help, but heres couple of photos from different angles.

 

Looks like left over Thanksgiving pie that has been in the fridge a year.

 

This looks like a job for electrolysis.

 

Perhaps, but I would never pull it off.

 

The coin is so far gone that trying something radical won't result in the loss of a great treasure. I'd try soaking it in vinegar. That should dissolve the thick green stuff, although the original surfaces may be too far gone for this to help.

Use plain white vinegar. Dab/rub it gently with a cotton tipped swab every half hour or so. It may take several hours. Replace with fresh vinegar periodically if the old vinegar becomes very colored. Once you've reached the desired effect (hopefully revealing some details), soak it in distilled water and then in a some alkalinized water (a teaspoon or two of baking soda in distilled water), and then several changes of plain distilled water before drying it thoroughly.

(LOL, I had a typo, now corrected: cotton tipped squab. Yeah... scrub that coin with some poultry, that'll do the trick! )

 

I must admit, that since last night, I managed to perform something with a coin, that resulted in loosing all the green stuff(and some brown patina) without negative influences to the coin.
I can now see most of the bust, but not the front of the face, which is still under brown patina.
