925 Silver – Windows of Heaven – Notre Dame Coin Graded a Perfect PF70 by NGC! This is the only coin to make a perfect 70! Yes that is correct, population of only 1! The Slab is in very good condition, but does have some faint scrapes on the front of the slab (slab/etc may have very minor imperfections from storage/display, see photos). The coin has been verified for metal content by a sigma metal tester and NGC. All photos are of the actual coin and slab you will receive. Please take a good look at the photos, as they are also part of the description. This lot is one of a few I will be listing from my collection, so make sure and check out my other listings as well. We have done our best to accurately describe all of the items in this listing, but we are by no means collectable coin experts. Thanks for taking a look!
