Up for bid is this lot of 6 1987 Topps Baseball #366 Mark McGwire cards. This 6 card lot is NM+ Mint condition with great centering, good color and crisp sharp corners and edges. I'm not a professional but they are probably worthy of being graded. This is McGwire's rookie card which is now 37 years old. He played 15 years and was a 12 time All Star while hitting 583 home runs. These would make a great investment. Please see my other sports cards, toys and collectibles.
