Product Name: Vintage Pokémon card lot retailer 2011 2012 Dark Explorer 450+ Full List Available
I am not a collector and obtained these in a box lot with other items I wanted from an estate sale. They appear unused, like a new deck retailer of cards but please see photos. There are about 450+ total cards, a tin, a red coin, a board of coins unpunched, two paper game sheets, boxes, etc. I doubt the codes were used but unsure of how to verify that!. Last photos are screenshots of the list- quantity, name and number.
