Mark McGwire – 1999 Topps
This is quite an untraditional card. Topps printed 70 different variations, believe it or not, one for each home run McGwire hit in the previous year. The different cards were put randomly in packs. It was the luck of the draw as to which one you would get. A lot of the cards are worth about $15 not including the one portraying home run number 70. That card sells for approximately $100 to $125.

Ty Cobb – 1909 T206 ‘Bat Off Shoulder’
Any card from the 1909-1911 T2016 set is bound to be very valuable. However, the Ty Cobb card tends to fly under the radar. The “Bat on the Shoulder” variant is a little less valuable than the “Bat Off Shoulder” counterpart because more high-quality copies of the latter have surfaced. The prices of these cards vary a lot, but you can expect a copy to go for six figures.
