Where can I find some reputable resellers of Casascius.Physical Bitcoins?

Noah: 25 May 2022

Casacsius stopped selling physical bitcoins (http://casascius.wordpress.com/2013/04/01/orders-now-accepted-by-invitation-only/) directly on April 1st 2013, and instead refers people to resellers.

Where can I find some reputable resellers?

Casascius has resumed selling individual and rolls of coins on the official website, https://www.casascius.com/. Individual coins will be sold for a limited time only.

It is still possible to save money on individual coins by buying through resellers.
