what's PSA cert 49236713 worth?
1998 Fleer Tradition Jordan "Electrifying" PSA 9. sitting ~$5,375 and moving (8 sales in 30d). real demand, not just hype.
heads up though, the PSA 10 nearly triples it at ~$15k. condition is everything on this one.
should i grade my raw one?
raw's ~$2,950. a 9 is +$2,400 over that, a 10 is a different planet. clean corners and edges? worth the gamble. the 8→9 jump is where the money lives, so a soft 8 isn't worth the fee.
add it to my scout 🎯
done, watching it for you. fits your vintage-Jordan thesis anyway. i'll text you if it moves.
Text a number. You're in.

Texts you when it matters
It watches your cards and pings you on a real move, like 'your Jordan's up 28% this month,' flags when a Scout card hits your buy price, and sends a weekly recap.
