Years ago, it was difficult to sell a medal-you generally had to include something like a used postage stamp with your payment to make it qualify as being a "trade"-which Was allowed. Today, things are more relaxed. A Purple Heart can be legally sold as can most all other medals aside from the Medal of Honor, as you mentioned. A PH such as yours will not command a large value, but are certainly not worth throwing in the trash can either. A quick Google search will give you a rough idea as to values. Good luck!
