I had good fun at the coin show and even brought home some new pieces. I wrote about one, the 2014 Centenary of & Submarines , here: https://coinofnote.com/2014-centenary-of-military-aviation-submarines-pnc/ A PNC with two coins to celebrate two centenaries!
Did you know that the first was built in 1620?
