I have a Ted willams, Nolan Ryan, hank Aaron, Eddie Murray, and ken Griffey jr. 23kt gold baseball cards in the original box with certificates of authenticity. How much are these worth?

Border gold or all over, they seem to be selling for about the same.
Between $4 - 9 each is what they sold for on eBay in the last month.
Sets in box don't seem to increase the price.
The gold is electroplated (EP) or foil, a minuscule amount, and the cards are not worth buying for the gold.
