Selling Tips
Do not grade this card; the condition flaws and the player's market value do not justify the $19-$25 grading fee. List as '2007 SP Authentic Miguel Montero RC Auto Patch /75'. Use clear photos outside of the scratched top-loader to show the actual condition of the foil edges. Highlight his status as a World Series Champion in the description.
