Yes on die crack. I would say no on additional value. If you think it is especially attractive, you can keep but it is a rather common occurrence on dimes.
NAV, but a nicer than average die crack and it's thru the date, to boot! Don't recall seeing that particular crack on that date.
Dear Mr. P. After reviewing your records, we have discovered that you have not declared this $1,000,000.00 on any return. For this reason, we are requiring payment including principal, penalties and interest in the amount of $543,210.00 to be paid within 10 days of receipt of this notice. Have a nice day!
WOW, that is the elusive "spitting neck" dime. One sold on Etsy for $27,000, NOT. Just kidding to try and lighten my lousy mood. Welcome to Ct, (two years too late LOL) and nice find. I'd certainly put that in a 2x2 and hang on to it. You may find that person that collects just die cracks and is willing to pay nicely for it. Good luck.
