It sounds like you have some air cured Virginia on your hands. Burley always smells good, even when curing in the barn. The leaf also looks to be a Virginia, based on its color and shape.
As for what to do with it? It probably needs some aging so you can do one of several things
1. Build a small kiln by putting a light-bulb in a box, add a thermostat set to 120 degrees and place your tobacco in a sealed jar into the box for 3 weeks.
2. Use the "Dashboard" method of aging. To do this, place your (slightly damp) tobacco into a plastic bag and lay onto the dash of your car. Let the sun shine on it for a few weeks while venting once per day.
3. Seal it in a bag for a year, checking occasionally to make sure it has not dried out.
If it is air cured Virginia it will be somewhat bland tasting compared to it's cousin the flue cured type. By air curing, all of the sugars that would normally be "set" by the high temps of flue curing will have been lost by enzymatic and bacterial action.
If you don't like the smoking quality of it you could always try your hand at making some dip.
