I'd probably save one as a collectible, throw one on my laptop, give a couple away to people who I deem worthy, maybe post it on the bumper of my car, throw one on a reusable water bottle or my phone since I carry that everywhere, remove the gold and replace a steemit sticker on a hat, throw it around in a strip club like it's currency and collect more!
Pretty cool idea... why didn't I think of that lol.
