PSA 10 copies of Heimerdinger, Inventor are asking $250 on eBay against a raw market price of $71, a 3.52x multiple. After a $25 grading fee and 13% marketplace fees, a PSA 10 would net about $131 more than selling raw; the graded copy has to sell above $100 to beat raw. That assumes a 10; whether your copy grades a 10 depends on its condition, which is the part TickerMint's verdict weighs for members.
The TickerMint Estimate for Heimerdinger, Inventor is $70.97. It is a fee-adjusted fair value blending TCGplayer and eBay data to estimate what a seller nets after marketplace fees.
