1964 Quarter Pattern - RB-1300, INCO

Coin Details

Description

The RB-1300 designation introduces another major alloy family in INCO's 1964 experimental quarter program, representing a third distinct approach to the silver replacement challenge beyond the 1000/1100 and 1200 series. Each major series number in the Reed-Brenner catalog typically indicates a fundamentally different metallurgical concept being explored. The 1300-series tested alloys with different nickel-to-copper ratios, alternative trace element additions, or novel multi-layer structures designed to achieve specific electromagnetic or visual properties. These pieces were struck at Medallic Art Company on genuine Washington quarter dies, maintaining the standard protocol that ensured consistency across INCO's entire testing program.

Rarity Notes

Extremely rare experimental piece from the 1300-series alloy family. Like all INCO test strikes, surviving examples are estimated in single digits per composition.
