German post-war inflation seen through Westfalen

I picked these notgeld up at my LCS yesterday. They're nice coins, but beyond that it's interesting to see how inflation escalated as seen through the denominations. Starting with a 50 pfennig in 1921, they were up to 50 million marks by 1923. All the coins are sized between a U.S. small dollar and a crown size, and most are aluminum. Note: I'm not sure if there are other denominations. These are the ones I got yesterday.
