Question
QUESTION: I have a gold Sovereign that weighs 7.9 g. George V on the front but MOM 21 stamped behind neck. It has George Slaying the dragon on the back with date 1918 B.P
My question is I cant seem to find this coin in any book

ANSWER: Hi Jim,
The 1918 Sovereigns are listed under Australia, you would not find this by looking at identical coins under Great Britain or South Africa in your coin book.
The "MOM21" is something that was done privately. As such, the coin would be worth gold bullion value. Normally they are worth 15% more in this condition, but the stamping takes away the collectible premium.
Thanks for the question! =)

Answer
Hi Jim,
Sorry for the delay, I've been swamped with questons latetly.
Ok, it looked like it was stamped into the surface, but it's often hard to tell from pictures.
After doing a little more digging I realize that your coin is a replica. Now, it is the correct weight and looks like genuine gold. I managed to find some references to coins marked "Mom21". They are cast, and all the ones I have been able to find were not genuine gold.
Your coin has the correct weight (though I don't know if the size is correct) and looks like genuine gold.
I have attached a picture of what a gold-plated version looks like after being circulated.
A solid gold version is not known, but would be worth the same as a genuine coin (15% or so above gold bullion value). A typical gold-plated version would have a minimal value as a curiousity.
Thanks again for the question! =) Hopefully this settles you long search to figure this coin out.
