    I think it is rather because it is never used alone and does not really represent one hundred, but a multiplier of variable value.

    C' represents below a reversed C.

    |C' = D = U+ 217E = five hundred
    C | C' = CD = ↀ = U+2180 = M = one thousand (cf. mille in French)
    |C'C' = DC' = ↁ = U+2181 = five thousand
    CCIC'C' = ↂ = U+ 2182 = ten thousand
    CCC|C'C'C' = hundred thousand -— not coded in Unicode, why ?

    A million is represented by a Saint-Andrew's cross surrounded by a canopy |¯|, it is not coded I believe. I don't know why. I have representations of it.
