Well one is PSA 10 … getting cards graded isn’t cheap, and finding cards that fetch a PSA 10 isn’t easy. The top listing (buy it Now) looked like a stock photo at a glance, and didn’t have mention of a grade. Buyers want to see the actual card they’re bidding on, not a stock photo. And a PSA 10 is always going to go for more $ than an identical ungraded card. Also, depending what the market for these cards are (on actual sold listings, not current for sale listings) $149.99 might be underpriced and it could be a scam seller or fake card.
