I'm really confused by this auction listing. It's a PSA 6 T206 Piedmont 150 Schulte Front View. It's already up to $1200 with an estimate of $4000. Am I missing something with this card? It's just a regular Piedmont 150. I know it's a high grade but I feel like there's something obvious I'm not seeing about it. Doesn't seem like a $4K card.
