Demetrious Johnson [Silver] #21 2012 Topps Ufc Knockout Ufc — Card Value

Which version do you have?

If you just want the card, the Standard version at $3 is the cheapest way to own it. The Silver ($10) and Gold ($4) versions offer slight premiums, likely through unique printing or limited edition status, though the differences are minor based on these prices. Save your money with the Standard version unless you specifically want the visual appeal or perceived rarity of the Silver or Gold versions.
