Another little cleaning job

Chrsmat71 sent me a coin to play with, so I did.

Before pics

This was a tough little cookie. It took 3 soaks, the green stuff looked to be in layers. I could pick at it a little more.

As it looks now. Slightly better in hand.

Quite a change! Well done! I managed to similarly clean an encrusted Constantius from London, and I have a Maximinus that I've tried cleaning as well but have had no luck with that one.

 

My method doesn't always work. Sometimes it is a partial success. I need more green coins to practice on.

 

Bought it thinking it would be easy like with my Constantius but its proven so frustrating for me. I had it soak in Verdi-care, hydrogen peroxide, and in acetone but have hardly made a dent in the green. I'm wondering if I should heat it up while it soaks?

 

Going to PM you.

 

fantastic result Pishpash!

I have a galba dupondius with a incredibly thick patina/layer of green. Maybe it can be helped too.

 

@Eduard post a picture of it. I only use my method that involves the very hard green deposit that defaces the coin.

 

Big improvement!

 

Pishpash, thanks, here it is.
I am unsure whether this is just incredibly thick patina or a green layer of crud easier to remove.

What do you think?

 

@Eduard I would leave it alone. Yes the patina is very thick, it is still attractive.

 

Wonderful job @Pishpash !!!

 

i would say leave it

 

i'll look in my collection, ok?

 

Great cleaning job and very nice photographs!

You are an artist.

 

Nice going @Pishpash

 

Very nice! If you don't mind, can you share your method?

 

Came out better, intersting it hid the crack well on the before though.

 

@Mat, yes, in hand there was no indication of the crack prior to cleaning. The downside to cleaning can be that you uncover a can of worms (so to speak).

 

Don't forget, as an antique collector, doing away with the patina you do away with value! sometimes it may be required in extreme cases but other times it can be the worst that you can do...another thing is the chemicals you use can and will deteriorate the metal.

 

Sometimes the mineral deposits can disfigure the coin. I wouldn't dream of removing the patina. These deposits are generally on top of the patina.
