"Blast white" and even "MS+++" (whatever that's supposed to signify) can be
overlooked, but you really spoiled it by including that tired "....will make
a fine addition to any collection" statement in your description. A MS65
bust dollar might qualify for that superlative, but a common unc half
dollar? ANY collection? And to use BU, MS+++, Bright white, blast white,
and rich full lustre in the same brief description seems like overkill hype
based the average appearance of the coin in your photos.
Certainly you realize by now that most bidding usually occurs within the
last half hour of an auction, and that there's little chance any unc bullion
coin will not end up bringing at least its bullion value. Not to worry.
I liked that most of all. One of the most vivid descriptors out there.
