1964 Quarter Pattern - RB-1305, INCO

Coin Details

Description

An experimental quarter bearing INCO's RB-1305 alloy designation, part of the 1300-series tested during the critical 1964 silver replacement evaluation. This piece represents a variation within the third major alloy family explored by the International Nickel Company, with incremental changes to the base formulation established by RB-1300. The breadth of INCO's program — spanning multiple alloy families, each with numerous variants — demonstrates the complexity of developing a coinage alloy that could simultaneously satisfy requirements for striking quality, durability, anti-counterfeiting properties, vending machine compatibility, public acceptance, and production economics.

Rarity Notes

Extremely rare. INCO experimental quarters from the 1300-series are known in very small numbers, typical of the entire evaluation program.
