I have set up a community page on Facebook titled Münzen Westfalen 1921-1923 Coins and currency Westphalia 1921-1923 Notgeld. Please join. I am still working on setting up the display and the Zwittermedailes I have, are waiting to be submitted to PCGS since NGC doesn't do them, along with my Billion Mark die trials and misc Westphalia medals.
