Well I have 2 old ONE PENNY's the one is from 1911 and the other is from 1921
I'm sure from where the penny's are but on the back it says:
GEORGIVS V DEI GRA:BRITT:OMN:REX FID:DEF:IND:IMP:

If someone could just help me find out please cause I can't find info about that coin anywhere!!

Go to your local public library where there are books on coin collecting and coin values. Most of the entries have photos of the coins, so you can match your coins to the photos and descriptions. Sometimes the books are reference only, so either call first to find that out or just take your coins with you.
