Antarctica has no sovereign government and no independent monetary authority — no treaty, no territorial administration, and no population with transactional needs. "Coins" issued under the Antarctica name are novelty items produced by private minting operations exploiting that legal vacuum, sold directly to collectors with no pretense of circulation.
Plastic composition removes any ambiguity about numismatic intent.
