Close.

Rather than created, an object would have to be removed from
a pool in which another (or the same) object was placed when
the blinded token was signed.

Using the ERTP protocol, you could create a 'blinding agent'
that would sign blinded tokens in return for Purses
containing erights. Later, these signed tokens could be
redeemed for another Purse containing the represented number
of erights.
