This is the most common type of 1954 $10. In VG condition it lists at about $2 over face value.
If you wanted to get rid of it you could try and sell it on eBay. But after you add in the listing fees and shipping cost, you won't make $2 profit. You might break even or even sell at a loss. At the most I'd guess that you might net 50¢ on it, but not much more.
If it were mine and I wanted to get rid of it, I would just spend it. The entertainment value of spending it in a coffee shop and seeing the 17 year old barista's reaction to it would be worth more than the 50¢ profit I might get on eBay.
Come to think of it, if you don't want to keep it as a souvenir, I'd spend it sooner rather than later. I don't think that its collectible value will ever increase to much beyond face value. And the buying power of it at face value will go down over time due to inflation.
