discharges or otherwise affects any valuable legal right, privilege or
obligation shall be deemed the greatest amount of economic loss which
the owner of the instrument might reasonably suffer by virtue of the
loss of the instrument.

which is provided for charge or compensation, the value shall be the
value of the property stolen in any consecutive twelve-month period.

fifty dollars.
