I have 50 copies of base card 82 from POA. (My case had eccentric collation.)
Of course, there are the Order Form pack inserts from POA and GOF.
Not counting foils/puzzles, the only Potter chase I have of note are a few threes. I've depleted my supply of the relatively "easy costumes and props" through birthday and holiday giftings. I'm down to a single Sleeping Bag now! And two Lupin's (heavy) Jackets.

For Lord of the Rings ROTKU, though, I still have a combined 37 of Merry's Rohan Cloak and Sam's Wedding Jacket. And 13 of Éowyn's Coronation Dress. Shipping charges were cheaper back then ...
