Gold-plated items, no appreciable resale value.
Altered 2007 silver eagle with gold is scrap metal to a collector, $20 at best.
Steel cents and minors, multiply face value by 15, e.g., silver dime worth $1.50.
"Rare coins" are not rare, presentation set, $5.
1800's set, $12.
Double silver morgan set, $50.
Good luck.
