That is a nice set. Bicentennial coinage fueled my young numismatic fires back in the day. Good to see them getting a little attention....... I haven’t pulled up recent auction prices but I would guess that set may fetch around ten bucks....... Now that cellophane is US mint issued. Keep them in that cellophane.
They produced a lot of these, and not much demand now for them. But, in high grade, they can go for good money. You would need to have much experience in grading each of the coins though. Welcome to C.T.
Yeah, this is the old "good news, bad news" situation. That's a really nice set of these iconic coins. Unfortunately, they are so iconic that they prompted many, even non-collectors, to acquire sets & put them away. So now there are so many of these in pristine condition. I have a "non-collector" friend who still has 11 sets!
