Vintage T-Shirt Forum & Community Authentication Appraisals

While going thru my crowded T-Shirt drawer I found this on the bottom. Forgot I even still had it, but a few searches on the internet found some or sale for High prices. but just for sale, not sold. So wondering what it might actually be worth.

It's worn, but still in good shape. No holes, stains, or ripping around the collar or cuffs. It is legit, because I was the one that bought it at a NIN concert. It's printed on front and back. The NIN logo has worn over the years, but really just proves it's vintage. Also has printing down one Sleeve. Size is XL
