I have this E.C plaque along with others having the £ monetary unit... There are others E.C pieces being found in France w/o any monetary unit.

Both of these E.C monograms are not exactly the same, though both the E and the C are side by side with a period (.) between them.

I have no proof that my E.C plaques and jetons which are w/ and w/o the "£" are from the Eccentric Club except for this possibility
