Roll Coins

When collecting coins is it better to buy a roll of each coin from each mint?

or just buy single coins that is cased from each mint?

It is a matter of cost and what you want.
In MOST cases, you can NOT buy directly from the mint and would need to go through a dealer.
(I get “new” releases, such as “gold” dollars in “mint” rolls at my local bank, actually from a bank supplier and NOT uncirculated BUT never opened.)
