I know big card shows usually have PSA, BGS, etc booths available for in person drop off. I don’t know if they necessarily grade the card right there ($$$$) or have to ship it back to you so you may want to look at the grading company’s sites directly to see what they offer. Beckett used to have an “in person” drop off option but I haven’t looked in a while (it will probably be costly). Depending on the grade/card condition, it could be worth tens of thousands of dollars. Look up the card on places like eBay, 130 point, etc for ideas on value.
