Casascius coins or bars or Casascius anything are what started it all, like BCB said it’s going to go down in history as the first “physicalBTC” which helped many who learn better visually,  grasp the BTC concept. The growing popularity in this collecting is certainly not hurting.

I think funded Labryths are great. It’s a relatively small amount that makes for an awesome safe to store it for the long haul as well as keeping the funds away from yourself. Who doesn’t love the funded Cas coins, and how many people are going to cash in their .1BTC coins anytime soon?
