If you upgrade a Status Marker, you pay only the difference when you upgrade (i.e. upgrading a Protectorate to a Possession costs £20 (£40-£20).
Military Markers may not be upgraded, downgraded, combined, or broken into parts, but can be only built or destroyed.
If you downgrade/remove/destroy any Marker, you do not get the money back for it.
Canals cannot be destroyed.
