These are the 10 cards in my collection that would most likely have the highest resale value.
#10
1996 Score Select Certified Mirror Gold
Only 30 copies were produced of this landmark issue, which featured the first "rainbow" parallel set. The Mirror Golds stand the test of time for their aesthetics and rarity.

#9
2004 Leaf Limited Bat Barrel
Anytime you are talking about game-used bat barrel cards, you're talking serious dough. And Grace doesn't have many available. This card is numbered #2/2.

#8
2005 Upper Deck Artifacts Dual Laundry Tag / Auto
This unique #1/1 card features two prime tags, taken from the measurements sewn into a game-used Cubs jersey, and an on-card autograph. That's an unbeatable combination!

#7
2005 Playoff Absolute Memorabilia Red Prime Jumbo Patch
The 2005 Absolute Jumbo Patches are widely regarded as one of the greatest game-used sets of all time. Some serious set collectors would love to get their mitts on this card. Grace was one of the few players to have only a #1/1 jumbo patch.

#6
2004 Leaf Limited Threads MLB Logo Patch
Grace has only 2 MLB logo cards ever made, and this is the only one that features just him. The other, in 2005 EX, is a dual with Rafael Palmeiro.
#5
1998 Donruss Crusade Red
A landmark ninety's set that still has player and set collectors drooling over its beauty and scarcity. Only 25 copies of this card were produced, but finding one is much harder than it would seem. It took me 10 years.

#4
2007 Topps Sterling Letter Patch
A full game-used nameplate letter from the back of an Arizona Diamondbacks jersey. Only five of these cards were made, one for each letter in his last name. Being the first letter, this card carries a slight premium.

#3
2003 Donruss Signature Inkredible Quad Arizona Diamondbacks Autograph Card
Featuring the signatures of four contributors to the 2001 World Champion Diamondbacks, this card commands attention. Along with Grace are autographs of Randy Johnson, Curt Schilling, and Junior Spivey. Both Johnson and Grace are considered tough autographs, so having both together on a card is special. 25 copies were produced.

#2
2005 Donruss Leather and Lumber Bat Barrel / Patch
Combine a multi-color patch swatch with a game-used bat barrel, then limit it to a #1/1 and you have the recipe for a high dollar card. Even without the M and the E, it's a card to make any collector jealous.

#1
2004 Upper Deck Ultimate Collection Ultimate Signatures Quad Cubs
Put the signatures of my four favorite Cubs on one card, and it's sure to be the crowning card in my collection. That's just what Upper Deck did on this beauty, with two Hall of Famers in Ryne Sandberg and Ernie Banks, and another possible one in Ron Santo. Grace sure looks good in that company!
