Old coin(s) Hammered ???

Hello

I have some old dirt coins. I know they are in bath condition but I have them for FREE.
Anyone an idea for this coin? Diameter is 20mm

Anyone an idea how to clean (hammered) old coins?

Thanks for your help.



Regards,
Kenneth

Thanks !
Can you help me with the other coins ?
But they are dirty, how can I clean them ?

I think they also French but I'm not sure.

Where is the other coin?
To clean them, put them in motor oil for a week...

They are too dirty to take a good picture.
I need first clean them

Ok
If you want, you can also send them to me  

If they are silver, try spitting on the coin (both sides) then sandwich between silver foil and rub gently. A smell of rotten eggs will be given off if coin is of good silver. Then wash under water.

Please don't try this method. Leaving them to soak in oil for while sounds much better. You need to avoid rubbing the coin as it will cause wear.

I would agree with you if the coins were of a decent grade but it looks too worn and broken to be of any real worth.

Yep they are in a terrible condition.
