The 2018-19 SP Base Set Robert Thomas Gold Rookie Authentics Signature #137 is a Hockey card (Gold Rookie Authentics Signature parallel) released in 2019. Ungraded copies carry a market value of about $40.42.
An ungraded copy is worth around $40.42, a PSA 9 around $50.87, a PSA 10 (Gem Mint) around $77.77 and a pristine BGS 10 around $101.00. The gem-mint premium is modest (about 1.9× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($40.42) and top-graded ($77.77) 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.
