I don’t think a red book is applicable. I’m showing the 2021D clad half at 10K as of a few days ago. Sales end tonight.
Uncirculated MS-63 the coin is worth $2. Either I can't find the mintage numbers, or they haven't been released, but I assume it will be 2-3 million.
from https://www.coinworld.com/news/prec...ordering-half-dollars-for-general-circulation ... So far in 2021, production totals 7.7 million half dollars struck at the Denver Mint and 5.1 million pieces at the Philadelphia Mint, suggesting a possibility that the 2021 coins may be supplying orders for circulation.
Sales through 12/26 is just over 10K. It goes off sale tonight and if I recall correctly the current low is or was around 15K. But I haven’t tracked these in awhile. So this coin could end up being the lowest mintage modern commem by a landslide.
The 2016-D National Parks half was hyped to be the lowest mintage at the time. I haven't kept up with it since then. 21,328 is the number posted on the US Mint site here https://www.usmint.gov/about/produc.../2016-national-park-service-100th-anniversary. Looks like the 2017 Boys Town was lower at 15,561 and then the 2018 Breast Cancer Awareness at 11,301 even lower. The 2019 American Legion 100th was then 11,429. I don't know if I trust any of these numbers or any of the hype. The 1995 Civil War Battlefield was 10,614 but what was in the "young collector's set" that sold 51,947 and does the 10,614 number include that or the wrist watches or money clips? Is there a definitive source for any of this? Even the mint site tagged above stops at 2019.
