For future items like that I'd recommend getting rid of the reserve and just starting the minimum bid at the least you want to take for the card. In my experience reserves scare people away...they don't bother wasting time bidding because honestly the reserve is set higher than what somebody is willing to pay 90% of the time.
I have had luck on rare items setting it as a fixed price listing - buy it now or best offer.
