I recently acquired this Indo-Greek AE tetradrachm from a dealer in Missouri.
I love the detail, but the cleaning method left some really ugly colors. It looks much worse in hand than the picture.
I was wondering what folks would recommend for fixing?
- Leave it on a window sill for six months
- Darken using a product such as Deller's Darkener
- Artificial patination product such as JAX Green Patina
Leaving it alone is also an option, but I feel this particular coin could be very beautiful with an even tone. I am asking because I have never retoned a coin.
I am also curious to know if people feel this coin was cleaned chemically or by electrolysis.
