playoff contenders autograph question

[TeRRaPiNs56]

in the contenders set there are blue and black autos of the same players. does anyone know the difference between these two. are there others like red and such.... i've seen black and blue and do not know the reason behind these. let me know thanks.

some years they break it down by blue and black and each have a quantity...i have never seen or heard of a color ink other then blue or black.

Yeah its almost always black or blue. Sometimes one is harder than the other and sometimes they just don't tell you.

from my experience contenders does just blue and black with the black being the most common of the two. Back in 04 I pulled a Blue Willie Parker Rookie Ticket which was numbered to like 10 or something like that

of the blue and black, what are the print runs of each one?? does anyone know for certain which one is more rare?? KNOW FOR SURE! thanks
