Time signatures ¢¢ and cc

[Dan Eble]

I have a hymnal in which many songs have time signatures with symbols
"cc" and "¢¢" [doubled cut-time symbol].  I can't find any information on
these online.  Does anyone know what they actually mean?  Were they
common historically, or is this hymnal just using them ad hoc?

My hypothesis based on the context and the feeling of the songs as they
are usually sung is that "¢¢" is 4/2 (i.e. 2/2 + 2/2) and "cc" is a misprint.
("cc" appears very rarely.)
