Yes, you are.  Norm did *not* mean constant dollar_type, but just constant.
You still are trying to get an implicit conversion from a universal real
expression to something of type dollar_type.  This is not possible, as noted
by Norm.

Oh, BTW, our system (DG) gives:
My dime is .102
Your dime is .078
which is wrong on two counts.
