Help with Penney's Marathon

Hi! I've been lurking for a while and am grateful that such a place exists.

I managed to get my hands on this hat today at a thrift store. While this is not the first Marathon I've got it is the first time I've seen the liner in this color. The hat is in pristine condition. So much so that I can't help but be skeptical in its authenticity. The liner is burgundy with gold lettering.

If anyone could offer assistance that would be greatly appreciated!
