I have a series 1953 it has the red numbers and seal, looks like when they printed it there was a mistake and down the front next to the president is a long red mark and on the other side of Jefferson there is a vague partial imprint of numbers. The marking run top to bottom. Is just worth 2.00 Don't want to give away by accident if worth more. Thank you

A used $2 red seal bill isn't worth much, but it is worth more than $2. The mistakes, who knows, it depends.
Take a picture of both sides and show it here or on the Money Discussion Board on eBay.
Or just go through all the $2 red seal bills listed, and sort by Time Ending Soonest, so you don't get too excited by the listings that are way overpriced.
