To pawn your DS games, first, gather the games along with their original cases and manuals, as this can increase their value. Visit a local pawn shop that accepts video games, and ask for a valuation. Be prepared to negotiate the price, and ensure you understand the terms of the pawn, including any fees and the duration of the loan if you plan to retrieve your games later. Finally, bring a valid ID, as it may be required for the transaction.
