Lebron 03-04 Topps Chrome PSA vs. BGS

[janton79]

I have a PSA 9 2003-04 Topps Chrome Lebron James card and I was thinking upgrading to a BGS 9 or PSA 10. In looking at prior Ebay sales, I was really surprised to see the price variance.

Recent PSA 9's have sold for around $800. BGS 9.5's are more than double that, coming in just below $2000. And PSA 10's have been in the high $2000's to mid $3000's.

What's the reason for the spread? Seems out of whack compared to other cards. And what do you think the best value is for a long term hold?
