Would guess that it'll be one old design one new design, but I don't think they've released any info on it yet
Yes there will be the old design and new design silver eagles for 2021 they will probably sell midd 2021 they haven't been saying much about this/ confirmed sale date.
So the old design will only be minted at the Philadelphia mint for 2021 no s or w for 2021 the old design.
Gov.mint are selling regular ones for $30-$35 slabed ones in 69-70 are going for $40-$50 at gov.mint and other gimmick sites.
It's literally on the product schedule https://catalog.usmint.gov/american...coin-set-21XJ.html?cgid=2021-product-schedule
Judging from product codes on the schedule and history, I am GUESSING this will be the 35th Anniversary Set and both will be the old design. Fingers crossed they do not make a mess of it like they did with 2019-S ERP and 2020-W WW2 Privy. Bad website and lost orders are something they really need to work on for these special releases. I would also like to see they reward their loyal customers with a program something like RCM does. Early access to special sets would be nice for those of use who keep them in business.
