Don't worry. Most of my "paper" wallets are encrypted silicon, duplicated and off-site.

Those that are actually paper (travel, current transactions, etc.) I keep in money-sized ziplock baggies along with pertinent transaction details like dates, amounts, sources etc.

I also archive my old swept wallets with their records. Some of them even have bits of forkcoins I never bothered to scavenge. They're also in baggies but additionally sealed in Mylar.

Someday even those forkcoin "faketoshis" might add up.
