We consider two types of quotients of the integrable modules of s-fraktur signl-fraktur sign2. These spaces of coin variants have dimensions described in terms of the Verlinde algebra of level k. We describe monomial bases for the spaces of coinvariants, which leads to a fermionic description of these spaces. For k = 1, we give explicit formulas for the characters. We also present recursion relations satisfied by the characters and the monomial bases.
