Assuming I'm looking at the right one it's listed as $300-600. The only reason I wonder about the listing is because it's listed like this: "1972-73 Topps #195 Julius Erving RC/ (Forward on front,/but Center on back)". I don't know enough about the card, and haven't looked it up, to know whether that means this is an error card, or if all of his rookies are like that. If they're all like that, I don't know why they felt the need to add that to the listing. If they're not all like that, then I'm not sure why there's not another card listed without that specification.
I don't think it's just recent years. I've found discrepancies with Beckett's pricing since I started collecting. It's a big reason why I don't deal with BV unless it's a low-end card. On any mid-high-end cards ($20+ cash value), I go by past sales, where available, or comparable card sales (SV). The only exceptions to that are if I'm trading for a PC card that I really want. Then I'll kinda flow with whatever the other trader wants to roll with, as long as it's not too much of a lopsided deal in sale/cash value.
