Patina" If a coin (copper, silver, brass) were to be left in or on the ground it will get a patina (an oxidation giving a dark color to the coin)
Light" Light has two meanings one Light as the light of day and lite as it is not heavy (The color of the item was light)

http://en.wikipedia.org/wiki/Patina

you can choose the language from the menu on the left side of that page. They have a Ukranian translation.

If you have an android phone or tablet, you can download Google Translate from the Google Play store. It's free and you can add on many language packs for offline translation. I find it very useful when dealing with Polish and Russian customers. The language packs are very big, so it's better to download them through wifi.

I used to be able to buy ammonia from the hardware store, and clean my copper coins with.

I have sent yesterday answer. But I do not see it at forum. I repeat the answer once again, excuse me.
I was yesterday in mountains at the first place. But, unfortunately, I not found other fragments (similar to first). Could find only rusty splinters. But I have found the lost fragment of a sabre. But it is very rusty. What solution is necessary for deleting of rust?
The first brass fragment I have found not deeply under a ground (less than 10 cm). Probably during first world war the shell has thrown out this fragment on a surface. Therefore I shall be compelled to expand a place of search.
Tried to leave a streak on a porcelain plate. The found fragment leaves a more greasy streak than brass.
If my alloy has only copper and gold that percentage (my calculations) of gold is equal 4,27/11,2 = 38 %
Would be useful make the analysis on time of making of the mentioned alloy. A radiocarbon method .............
Thank You.
My best wishes

Try to use magnet to determine if its gold or not, if the coin magnetize its not gold but with a content of metal. . . .
