This happens if you buy "genuine 24K" gold leaf on Wish...
100 Sheets 24K Pure Genuine Edible Gold Leaf Foil Sheet 99.99% Gold For Art Crafts Design Gilding Framing Scrap. They even showed a gold bullion bar to promise you that this is read gold... It turned out to be a real fake like the 256GB SD cards I purchased the same day. Most people tolerate this because of the low price but they do not notice that this is a billion dollar market just by selling industrially faked products to take our money out of our wallet!
