Does it have a red seal on it? Typically the 1963 series with the red seal will go for about $20-$60 depending on folds, tears and whether it is circulated or uncirculated. Lower serial numbers (01603638 A) will also increase the value as well.
Hope that helps.... to get a good estimate based on the quality of the money, you can go here and see what this seller is charging. Jackson Creek Mint is very reputable.
