Finish & Decoration
Satin-to-mirror finish with a shell-like scroll at the tip of the handle. The design features a delicate beaded or threaded border characteristic of the Neoclassical/Directoire revival popular in the 1950s.
Hallmarks & Stamps
The reverse of the handle is stamped 'IS' (International Silver) followed by 'DEEPSILVER' and 'HERITAGE'. It also features the 'Inlaid' mark, indicating extra silver was applied to wear points like the back of the bowl or tines.
Construction Details
Mass-produced via die-striking from a heavy metal blank. Tines are cut and beveled mechanically. The piece is a single solid unit of base metal before being electroplated.
Functional Features
Four-tine design with a slightly wider outer tine for cutting soft foods. Ergonomic curved handle for comfortable grip.
Handle & Grip Details
Solid metal handle integrated into the piece. Rounded, spatulate end with raised decorative borders and a scrolled tip.
Craftsmanship Details
Industrial quality; excellent symmetry and consistent plating. Lacks the hand-chased depth of sterling silver but exhibits high-standard commercial die-work.
Authentication Indicators
The 'IS' logo and 'DeepSilver' stamp are consistent with mid-20th-century International Silver factory markings. The wear pattern is typical for silverplate of this era.
Origin & Manufacturing
United States; Meriden, Connecticut. Manufactured in high-volume industrial factories using advanced electroplating technology.
Era & Period
Mid-Century Modern / Post-War Prosperity (1950s). The design reflects a return to traditional elegance (Traditionalist) following the starkness of WWII.
Age Estimate
Circa 1953 - 1970s. Based on the pattern introduction date and the specific 'DeepSilver' branding style.
Cultural Significance
Represents the 'Bridal Registry' culture of 1950s America, where fine-looking flatware was a staple of the new middle-class domestic ideal.
Condition Notes
Good to Very Good condition. Visible surface scratches (patina) consistent with regular use. No 'bleeding' (base metal showing through silver), tines are straight and consistent.
Value Estimate
$5.00 - $12.00 USD per individual fork. Value is largely functional or for set replacement rather than investment.
Care & Maintenance
Clean with mild soap and water. Use a non-abrasive silver cream (like Wright's) for tarnish. Avoid the dishwasher to prevent 'plate bubbling' or excessive wear to the silver layer.
Similar Pieces

Interesting Facts
The 'DeepSilver' line was marketed as 'silverplate that lasts a lifetime' because International Silver used a process to inlay solid silver into the base metal at the most frequent contact points before plating the entire piece.
