I'd say it mostly depends on the era of the cards. You'd need a bunch of them from the 80's and 90's to equal just a few vintage-era cards. If you mean by Beckett BV, you might need about double BV for vintage and triple or more for modern (1980+) cards. Most people that care about BV look to buy for 25-35% of Hi BV, but will spend more for vintage in better conditions.
