JFS nahkampfspange silver or bronze?

[NH3CL]

Hi all,

Could you please help me to determine this badge bronze or silver?






Any advice for cleaning it?

Thanks in advance!

It's a bit hard to tell in this condition. The finish has been lost to time and the elements so any answer will be a guess.
Gut feeling based upon the recesses in the oakleaves is that it's toned and faded bronze but this is purely my personal opinion and guess.
