The coins for this year were manufactured as much as 6 or 8 months ago. The employees don't come in at midnight New Years Eve and start making stuff to sell in January. The same applies to the scams regarding First Strike, First Release, and all the other gimmicks used to drag cash out of uninformed collectors.
I just looked at the product mintage limit for the 2026 clad proof set. At 420,000, I'm not so sure it will sell out. I know many coin collectors, and the consensus I see is that they are not buying it, period. My mint set collection ended last year, so.
If he wants one minus the two pennies I'll give him a heck of a deal. I have one P+D purchased 190,000 Mintage!
