Your nickel (which is really 25% nickel and 75% copper) reacted with the vinegar (acetic acid) to form copper and nickel acetate.

You could use the solution to electroplate stuff.

 

It has happened to me. I thinks it's the copper that's dissolving that's turning it blue.

 

seems right there was a big copper colored spot acrossed the indians face

 

I think vinegar (or any other weak acid) preferentially dissolves the nickel. Nickel salts tend to be lighter greenish-blue, copper darker blue.

 

I know copper turns flames green thats why theres a tiny copper ball in green flamed lighters

 

How do you electroplate stuff?

Any body know if vinager will remove rust from metal dected objects

 

Know what the MSDS says about chemicals you play with. I suspect the quantities mentioned are smaller in effect, but someone may decide to completely dissolve coins to completion.

NiAc has the following in its MSDS:

Copper Acetate:

 

Good grief, never mind. Detecto made it sound fun until electrocution, coma, diahrea and death.

Yeah, death is seldom fun and you can't come back to blog, so take care.
