Topic: Double Sleeving: When, and which cards?
So I've recently realized I should start taking better care of my cards, and I was introduced to the idea of double sleeving, which really seems best. Based on reviews I've done, I'm going to go with the KMC Perfect Fits and KMC Hyper Matte sleeves. This is great for decks.... but my questions are:
When do you double sleeve? It only seems viable in decks (and binders, which I don't use). How do you keep your other cards properly protected (probably only 10% of my cards are currently in decks)?
Which cards do you protect? Do you put all your cards in *at least* penny sleeves, or do you just not worry about commons and only protect higher rarities? Or only cards worth a certain amount or more?
While I can get the KMC products in bulk, it's still going to cost 3.1 cents per sleeve and 7 cents per deck sleeve. At 10.1 cents per card, that's $6.06 per 60 card deck, $7.58 with a 15 card sideboard, and $10.10 per commander deck. As for all my other cards, if I put them all in sleeves, at 3.1 cents and over 10,000 cards (not counting duplicates past 4 and cards in decks)..... $310+. Ha. Yeah.
Note that I am part player, part collector. That is, I'm not a hard-core collector who'll pay $100 for a card just to complete my collection, but I'm also not a hard-core player who only keeps cards for my decks and trades/sells/trhows any other cards. So any suggestion to just cull my collection is not a helpful one, sorry.
I realize this is partly "personal preference", "depends on your budget", and the like. But I'm interested in community opinions and other people's thought processes.
