Canada POW/Internment Camp Unknown

These chits came from an advanced collector of Canadian POW and Internment camp scrip.

They originally came out of a Spink auction lot 447 July 16-18, 1986. They are stamped Censored C.R.C. 4 which probably stands for Commissioner of Refugee Camp. The previous owner thought they were from camp I (41) however I am not sure and haven’t been able to find any information. If anyone has any information about these, please contact me.
