The 2014 SP Authentic Zack Martin #18 is a Football card released in 2014. Ungraded copies carry a market value of about $2.31.
An ungraded copy is worth around $2.31, a PSA 9 around $14.99, a PSA 10 (Gem Mint) around $37.49 and a pristine BGS 10 around $49.00. That's roughly a 16× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
The spread between raw ($2.31) and top-graded ($37.49) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
