Collecting Coins

As title, I am hoping to purchase one of the new 2021 Morgan Silver dollars to add to my collection,I have a few from the 1800's including an 1893 coin minted in Carson City and an 1895 coin minted in New Orleans (both worth a few $$'s)
Is this webiste the official one?

Here in the UK there are a few companies that mint coins but they are not legal tender and are just worthless really

It appears to be the correct one

Surprisingly, Omaha's Durham Western Museum has an extensive coil collection from a RE Agent (Byron Reed/late 19th century). It's quite impressive:

Is it better to shop for silver coins or bullion?
Is there any places y'all would recommend for best values?
