They are nice cards. I get my values based on Ebay, Beckett, PSA, VGCV, and other websites.
I am not saying that is for sure what they are worth, but if someone wants to attempt to get them graded, they are high grade, which sell for 50-100 dollar range. The rated rookie sold privately for 100 in BCGS GEM 10.
Again, all subjective, so thank you for your opinion and question. We do do our research, considering this is what we do for a living.
