I have a Grady Sizemore authentic mint conditon autographed jersey. It is on the back on the four with a special autograph marker. I have never seen another jersey signed by grady. I have a certificate of authentication. I was just wondering how much this is worth. Thanks

Grady Sizemore is amazing..go tribe! but it's worth about 240 ish?

It's currently at $249.00 .

The current going price is between $235 and $250.

If the certificate is from a reliable memorabilia retailer that will increase the value a lot more than if it is from a private party. Card shops would sell a jersey like that for around $350. You could probably sell it for the same.

I believe it goes for about $100-$200. It could even go for a little more.
