[QUOTE="iPen, post: 2259942, member: 69760"]This is a bit random and I wasn't sure as to where to post this. But... How much gold is in a 23kt gold plated Michael Jordan and other similar sized cards? You can't legally advertise that it's 23kt gold if it's not, so it must be real right?... But, it's probably an "insubstantial" amount of gold foil plating the card. I'm curious to know how much actual gold is layered on top. Since 23kt is 95.833333333% pure gold, I figure the gold value is 0.958333333 x weight in grams x gold price per gram. Dimensions: I'm guessing it's at or near 3 microns thick... that means it's 2.5" x 3.5" x 3 microns on each side of gold of about 95.83% gold = 0.3272 grams x 0.9583 gold content = 0.31355576 grams of gold on each side = 0.62711152 total grams of gold.
