Extraordinarily-high relief (EHR) goes beyond what high and even ultra-high relief techniques can accomplish and elevates the subject matter to around 6 mm. The striking visual effect of each coin in your series that becomes more of a sculpture than a simple embossing is given an exceptional brilliance with innovative proof finish, making the silver shine like never before. Each coin features a multifaceted design built out of 435 polygons on the first coin, 498 on the second, and 450 on the third, that are crafted in proof finish to make each coin sparkle like a diamond.
Each coin features an ingenious approach to coin design. These are the first proof-quality coins struck with EHR – a new term in the world of minting. EHR is defined by an impressive relief that reaches to around 6 millimeters on a coin of only 36 millimeters in diameter and 1 oz. in weight. Ultra-High Relief coins barely reach 2 mm of height and standard relief coins remain almost flat in comparison.
Each coin’s multiple facets, composed of 435 polygons (on the first coin) to be exact, are crafted in proof finish to reflect light from various angles. The result is that each coin sparkles like a diamond. The highest quality proof finish combined with the EHR technique gives it an unequaled brilliance and sharpness, making it a world first coin of its kind. A lightly frosted background accentuates the sparkle of the central main design, giving its already dazzling subject even more emphasis. On the obverse, multiple light-relief facets provide similar luminous, reflective effect.
The exceptional three-dimensional of EHR allows each animal head to elevate mere embossing to a sculpture of each animal head. The relief is so extreme and pronounced that the modeling and tooling work had to be approached in an unorthodox manner. The engravers had to adapt their normal coin modeling procedures, CNC machining strategies and tool polishing methods to accommodate such an extreme relief.
First coin design:
The reverse sculpture by Claude Thivierge features a multifaceted wolf head built out of 435 polygons. The three-dimensional form protrudes from the flat coin, invoking both nature and geometry in its execution. The EHR plays an integral part of the design, introducing the coin as the first of its kind in the world – sharp, brilliant and doing away with the conventional flatness of minting. The obverse features the effigy of Her Majesty Queen Elizabeth II by Susanna Blunt.
