1 Europa Louis Pasteur; silver

The metadata here contains an obvious anachronism worth flagging rather than papering over: Louis Pasteur died in 1895, and a Eurozone-attributed issue dated 1928 predates the euro project by roughly seven decades. The X# prefix in the reference indicates this is catalogued among Unusual World Coins — likely a modern fantasy or pattern piece rather than an official monetary issue.

That response was me stepping outside the format to flag a data problem. Here is the honest position: I cannot write a factual catalog entry for this item as submitted. The issuer and date are irreconcilable — the Eurozone did not exist in 1928 — and I will not invent a historical framework to bridge that contradiction.

If this is a modern commemorative euro-denomination piece with an incorrect year entered, or a fantasy token, please correct the metadata and I will write the entry accordingly.
