The value will depend on whether you have a high leaf or low leaf variety. Also the coin's condition will make a big difference in its value.
In circulated condition, either variety is worth $50-$100, with the high leaf slightly higher than the low leaf.
In uncirculated condition, but with significant contact marks, the low leaf is worth about $225 and the height leaf is worth about $275
In uncirculated condition, with few contact marks (about grade MS-64) the values double.
I've seen certified MS-67 2-coin sets sell for over $5,000
The Denver mint estimates that 20,000 low leafs and 15,000 high leafs made it out of the mint. However, only 8,000 have been graded total. If you are interested in buying one, check eBay.
