This should be a sticky. 99.9% of the coins posted in this forum are worth either... 1) Face value or 2) Melt value
I think that is an exaggeration. There are many demonetized base metals coins worth much less than face value. And given that they are mostly alloys they are probably worth less than melt value due to smelting costs. So how about 90% as you say, 9.9% worth less, and 0.1% worth more?
Yea it seems like a Full Moon lately Huh? Folks staying up all night watching infomercials on what THEY WILL FIND IN THERE POCKET. That will make them rich without working.
