Newb here.
Can anyone tell me the purpose of the silver coins ?
Like.... if I collect a billion can I trade them in on a credit ?
If you type "what are coins for" in the SEARCH box over there to the right, you'll get a wealth of information. Hope this helps.

Short answer: No,
The longer answer, however, is: No.
