From SteveF:

First face of the coin: rotate 135 degrees clockwise. The characters are stand-alone.

Left symbol is Ning, meaning Peaceful

Top symbol is Shou, meaning Longevity

Right symbol is Kang, meaning Health

Bottom symbol is Fu, meaning Blessing

Second face: rotate 90 degrees clockwise. The characters go in pairs

Left and right make Nan (man) Duo (many), meaning “more boys in the family”

Top and bottom make Fu Gui, meaning “aristocracy”

Put them together and it’s an assertion that more sons put the family into the wealthy upper class.

The characters are all in traditional Chinese, of course, because they predate Mao and his idiotic (and murderous) policies.

The coin is probably worth a fair amount now, according to my wife.
