Do you know the meaning of Intrinsic Value? Has to do with the finance world, not a price of an object I want to share this webpage with you - https://en.wikipedia.org/wiki/Intrinsic_value_(finance)
You've read 'How to get rich with pocket change' and now think you're an expert. Your attitude won't get you very far here.
Intrinsic value is what the "metal" Is worth, the numismatic (collector) value is what you are asking about. This one was damaged (purposely) after leaving the mint. Worth face value only.
