This piece combines the high date variety quarter eagle obverse from J189/P226 combined with the reverse used on J149/P178. It is unclear if this is really a pattern design or a fantasy muling.
It is unknown if any of these were made using the low date obverse die. To view both dies, click here.
Fewer than a dozen are believed to exist.
4 obverse die trials JA1857-3/P3140, struck in white metal are also known.
