Mold Variations Collapse
Early Script Style
This is the earliest style mold with the script embossing style. Note the rounded dome and thinner, rounded wire groove lips.
Prismatic Style
Before the modern stamped style and after the script style embossing was the prismatic style embossed mold, shown here. This particular mold is slimmer with more shallow wire grooves.
Tapered Mold
Beginning in 1941, Hemingray switched to this style. This was the last style produced. Note the larger lower wire ridge that tapers down to the lower wire groove.
