Cello is a pain. Some of it's better than others but it sucks on most every display. I strongly suggest the It's your collection do what you like approach.
Quick answer for me personally. I'll buy a deck with no Cello fine, providing the seal is intact and hasn't been pulled. Then it's trickery and I don't care for that kind of nonsense. A broken seal can break a deal for me in a second, depending on the purpose I have for the deck. I fit in the going to use the deck category of collector.
By and large, people who collect tuck boxes tend to like their boxes protected by the cello wrap. I can offer up a deck that has no cello for trade and not get the trade done simply because of that. I don't sell decks so that's really not my dept. I can only use input from my experiences but....
In the end it's Modern Playing Cards we're talking about. Pull the cello if you like, your display will thank you. Just remember keep them clean and be happy. You're not likely to get whatever the ebay high is if you choose to resell them. You'll probably end up at a fair price though. None of them are really going to dent your bottom line if you choose to trade or sell them at some point in the future. If someone wants the deck, they'll make the trade or buy it. It's just that simple. Modern playing cards are modern playing cards.
Word of warning: On some decks with the heavy plastic seals, the cello is what actually keeps the things stuck down.
