I am new to the website and have been uploading my personal collection into the database over the past couple of months. While inputting numbers from my 2006-S Silver Proof set I noticed that the listed Kennedy 90% Silver (
https://en.numista.com/catalogue/pieces10867.html) mintage number was lower than the actual US Mint production numbers. I checked a couple of other numbers and they were not accurate to other sites which listed mintage numbers. I went to make the correction myself and determined that most of the mintage figures were not accurate, so I decided to not modify the web page. Instead, I thought I would reach out to the community to validate the numbers. I did do a spot against PCGS and NGC as well as the 2019 Standard Catalog and Kennedy Wiki (
https://en.wikipedia.org/wiki/Kennedy_half_dollar_mintage_figures) and the numbers do look inconsistent with database.
I am now hesitant on the posted mintage numbers and do not know if the data is reconciled from proposed mintage numbers to actual final numbers.
