The reference to the object will take up less space, although the
object itself will take up a lot more space that just a Decimal
property by itself.

A decimal takes up 3-12 bytes depending on the precision (aligned to
the nearest octet).
A shared object reference takes up 6 bytes.
An object has a fixed header part of 41 bytes, and also has a trailer part that takes up space as well.
