The Royal Canadian Mint’s latest privy mark Maple Leaf silver bullion
coin shines a light on Canadian involvement in a groundbreaking technology.
The Reverse Proof coin, which features a tiny light bulb privy mark
on the reverse, celebrates the pioneering research of Canadians Henry
Woodward and Mathew Evans, whose work inspired Thomas Edison’s
development of the famous incandescent light bulb technology.
This new silver bullion coin also features Mintshield surface
protection, a breakthrough innovation against white spotting, which
made its debut on the 2018 silver Maple Leaf.
Limited to a mintage of 50,000 pieces offered worldwide, the 1-ounce
.9999 fine silver coin is now available through official distributor
Manfra, Tordella and Brookes.
Its reverse features the classic sugar maple leaf reverse design,
which has become the signature of the Royal Canadian Mint’s Maple Leaf
family of bullion coins.
