Description

Aluminum with a reeded edge distinguishes J-847 from its silver and copper siblings in the diademed Liberty group. The delicate features of the star-free tiara design register with surprising crispness on the soft aluminum planchet, though the metal's susceptibility to environmental damage means surviving examples often show surface issues not found on the more durable silver and copper versions. Despite these preservation challenges, aluminum patterns from the 1870 Standard Silver program hold enduring fascination for collectors drawn to the juxtaposition of experimental metallurgy and meticulous die work.

Rarity Notes

R-7. Estimated 4-12 examples survive.
