i just found it interesting when the OP said he found a paperwallet in a zippy bag.. and also it wasnt just a passphrase but a QR code which is more of what i call a 'bitnote'(as demo's in image) rather than a paper wallet (hand wrote key on paper)
A (no longer trusted) paper wallet site used to sell CDs, tamper proof stickers and ziplock bags, basically making it a complete package to create and store paper wallets. Ziplock bags are quite common anyway, I use them for my phone and wallet too when cycling through the rain.
if you are concentrating on the zippy bag point you missed the point. it was the BITNOTE that was more interesting.
i did previously say that the topic creator can use an explorer to see WHEN the funds were confirmed to the address, and presuming that it was ages ago when value was way less, then that leans even more towards it being a discarded geocache.
EG paper wallets i own are not bitnotes they are just passphrases and private keys on paper. no design no logo(top creator mentioned logo) no instruction(topic creator mentioned instructions) so it appears thats its a bitnote not a paperwallet. and as such the main utility of bitnotes especially ones in zippy bags were not to put into your own drawer/safe for your own use but to be given out/given away.
so if the confirmed coin date was significantly in the past where the value at the time was not significant. then it leans more towards being a discarded geocache bitnote that the original maker doesnt care much for..
though if it is the case they could probably investigate anyone that did perform bitcoin geocache giveaways in that region of the planet and see if they can find the originator via people talking about doing geocache giveaways around the date of the confirmed coins
