not a lot. I have at various times picked up a holo parallel set (usually about 180 cards) of various of these VS System games for about $100, so individual cards are in the $1 to $2 range.
having another look, they might be the extended art promo versions so $2-$3 each. Not much different but worth knowing. Game cards aren't my thing but I really like the artwork on these sets and have picked up lots of them over the years
