Is the Shohei Ohtani 2018 Topps Base worth grading?

The 2018 Topps Shohei Ohtani base card currently presents a moderate raw-to-grade opportunity. With raw copies selling for $137.57 and PSA 10s at $508.28, a successful grade yields a net spread of $279.63, after accounting for grading costs. However, the 30-day PSA 10 trend is flat at +0.0%, indicating no recent price appreciation. Furthermore, the absence of sales data for the past seven days suggests low market liquidity. The primary risk factor is the unknown gem rate of raw cards, which could significantly impact profitability.
