A couple of coins in this series are listed in Exonumia. https://en.numista.com/catalogue/pieces40060.htmlhttps://en.numista.com/catalogue/pieces40061.html while the rest are listed under Liberia. The 6th edition of Unusual World Coins (c2011) lists the series with X# starting X# 17 and ending X# 63 (White House). The Liberia listings in Numista catalog for these use the X#. Krause 39th edition (also c2011) lists the coins within a range of KM# (836-950). I believe the coins have been de-listed from Krause and now appear with only X#.
Should the 2 Exonumia coins be moved to the Liberia listings?
Also, some of the coins are missing from both Liberia and Exonumia (example, X# 50 or KM# 938 Calvin Coolidge).
The coins are all 1 series so they should either be all in Exonumia or all in Liberia country listing instead of current split. Unusual World Coins lists them as medallic coinage, whatever that means. Numista catalog includes 21 as commemorative coins of Liberia.
Ok, I checked my newer (41ed. 2014) Krause and they are still listed as coins. So I now think Krause did some mistake and corrected it later on... I will move those two from Exonumia to Liberia.
Thanks very much Jarcek for your prompt determination of the situation. I want to thank you too for all you are doing to improve the catalog and contributing your ideas for the website. You have my deepest respect.
