Great, the millions I have in my drawer will be worth a fortune in a few years!
In short, they're worthless.
I used to save those stickers from all my Apple products in a separate bin. When selling/upgrading the Apple product, I wouldn't include the stickers with the old one and instead keep it for myself. I had several dozen different stickers. White ones, several colorful ones from the iPod Nano chromatic lineup, big ones from a Mac, small ones from an iPhone, black ones, gold ones, silver ones, on and on.
After about 15 years of doing this, I thought it was getting silly so I figured I would list them all for sale - I think I tried on ebay, craigslist, and on this forum. No bites. If I recall, I think I ended up giving them away for cost of postage.
I don't even bother looking at them anymore. They stay in the box just as they were when I receive the product, and they're shipped off with the product when I eventually sell it or trade it in.
