This rare 1 Yen coin from Showa Year 38 (1963) not only reflects Japan's unique numismatic history but also showcases a notable manufacturing defect, the burr lines, which significantly enhance its collectability.

Coins with such imperfections are highly sought after by enthusiasts, as they represent the quirks of early minting processes, contributing to a deeper understanding of Japan's currency evolution.

Given that these pieces are from 1963, they fall into a vintage category that appeals to collectors interested in post-war Japan, where coinage was frequently updated.

The current bid reflects a fair market value for such unique artifacts, particularly appealing to collectors in Japan seeking authentic and rare items for their collections.
