Magic: The Gathering collectors can acquire uncut sheets of cards through eBay auction for chairty now.
The auctioned for twenty uncut Magic sheets kicked off at 2:00 AM Eastern Standard Time on October 23, and there are still seven days left before the listings end. The collection of assorted rarities includes sheets from sets such as Modern Masters 2015, New Phyrexia, Unstable, and From The Vault: Realms among many others. The auction is also offering a pair of uncut sheets from the original Commander preconstructed decks from 2011 (Counterpunch and Devour for Power). If you're thinking of framing these sheets, they are sized 30" width by 38" height, with each sheet having 100 or more cards. The uncut sheets came from Wizards of the Coast's vault for charity.
100% of proceeds from the auction will be donated to the Extra Life, a charity organization that raises money for children's hospitals through gaming initiatives, with these sheets specically benefitting the Seattle's Children Hospital. Each bidding started at $1.00 USD and they are all available internationally.
The auction for the Innistrad sheet already has a current bid of $2,000 USD, and I expect most of these sheets will probably be sold for more than $1000 each.
