not sure of the cost, probably $15-$25 to get it in a red flip holder. i would get it graded...you're eventually gonna get it graded anyway so might as well do it now. if you wait down the line the authentication fee will only go up with the rising value of the card. that crappy card has doubled the value in the last 2-3 years because people are buying them up and getting them signed.
edit: when i first saw the faded sig my first thought was to get it signed again at $275 then have it slabbed...not sure if psa will charge you 2 fees
