benefits of mono-ply plated steel

The Benefits of Mono-ply

Mono-ply from The Royal Mint offers significant benefits over other coin and coin blank products.

Mono-ply technology

Mono-ply, also known as full plate, technology is the internationally recognised and accepted standard for plated coins and coin blanks. Countries across the world have adopted this method of plating, including:

•United Kingdom




•South Africa


Mono-ply is a single layer of material that is electroplated directly onto the steel core, which results in a very strong bond between the plated material and the steel core. The Royal Mint’s mono-ply coins and blanks have typical lifetimes of 25-30 years in circulation.

Superior quality from the world’s leading mint

The Royal Mint is the first choice supplier to around 40 countries every year, and uptake of mono-ply plated coins and coin blanks has grown since their introduction in 1983.

Low cost manufacturing, lasting quality

Compared with homogeneous coins or blanks, mono-ply plated coins and coin blanks from The Royal Mint result in significant cost savings and usually last 25-30 years in circulation.

High process yields

The mono-ply plating process employs fewer steps than other plating techniques and offers very high process yields, with minimal scrap and consistent quality.

Proven quality and supply

The Royal Mint has a recognised track record of supply, quality and on-going technical support.

Accreditations ISO 9001:2000, ISO 14001 and ISO 50001 demonstrate commitment to quality, environment and energy management. For further information on accreditations achieved by The Royal Mint, please visit the Information Library.

A range of security features

If counterfeiting is an issue, a wide range of security options is available to suit requirements and budgets. These include intricate latent features, edge lettering, lettering within a groove and micro-lettering.

Superior wear and corrosion resistance

One of the key benefits of The Royal Mint’s mono-ply plated steel compared to other plated products for circulating coins and coin blanks is the superior wear and corrosion resistance, which supports a long lifetime in circulation.

World class manufacturing capacities

Large scale production facilities on a single site are capable of meeting capacity requirements. On-going capital investment ensures that increasing demand for mono-ply products will not compromise quality or delivery.
