Hi everyone. I'm new to coin collecting so need some advice on a coin i found in a job lot. I believe it to be the 1922 Penny with the Britannia reverse from 1927 which i know is rare. It is a little rubbed but i believe the gap above the 1922 along with Britannias arm and the way it slopes up (along with it being thin and not muscly like the original 1922 reverse) gives it away. The border teeth seem to be rubbed however if you look next to the 1922 the teeth seem alot more obvious there. Can you please confirm if this is right or not? I have been made an very good offer by a dealer who is convinced it is right i just need to know whether or not to accept it and what the value is if its genuine?
