Adélie Land has no permanent civilian population, no local economy, and no practical need for circulating coinage — which is precisely why this issue exists. Like similar fantasy or semi-postal numismatic issues attributed to remote French territories, these pieces were produced for collector sale rather than any genuine monetary function, authorized under the administrative umbrella of the French Southern and Antarctic Lands (TAAF) as a revenue mechanism.

The X# prefix in Krause's catalog system confirms its status as a non-circulating or doubtful issue.
