25¢ 2014 "Doubled Die"

Mass production

Speed meets precision

The Winnipeg Mint is Canada's high-volume coin production powerhouse. Here, the industry's most technologically advanced processes and equipment produce up to 15 million plated coins each day for Canadian and foreign circulation. Our adherence to the highest manufacturing standards is what makes the Royal Canadian Mint a valued provider of coins to countries worldwide.

How circulation coins are produced
Circulation coins are minted using the world's most advanced minting techniques, patented technologies and rigorous statistical sampling to ensure the highest quality standards.

Producing blanks
Large coiled strips of core steel are fed into a high capacity punch press, which can produce over 13,000 blanks per minute!

Refining the raw materials
The core metal blanks are deburred to remove any rough edges, then rimmed (a raising and slight rounding of the edges), annealed (heated to better receive the strike), and cleaned.

Enhanced security
Electroplating is the practice by which steel coin blanks are coated with nickel and copper plate for protection. The Mint's exclusive patented multi-ply plating technique is the world's only multi-ply layer process that can match the electromagnetic signature of any traditional alloy coin - an enormous security advantage for the coin-operated vending industry.

Exacting standards
After plating, the coins are dried, polished and then sorted by a state-of-the-art inspection camera which examines up to 180,000 blanks per hour for blistering, colour variations and surface defects. Now the coins are ready for striking by a high-speed coining press. Once the coins have been rolled and wrapped, they are shipped to the Mint's coin pool sites across

Hi SPP-Ottawa, can you tell me how you came to this conclusion?

If I look at the rim beads they do not look like MDe to me.

Below is an illustration to show how I see it. The doubling of the 2014 quarter extends outward from the relief (highest point) of a normal bead, where for Mechanical Doubling the relief is always smaller than normal.

Actually it can because a single squeeze is done in progressive successions with continuous pressure being applied, making it at least 2 squeezes or more in one. Slowly builds to max pressure.
Old way was squeezed a couple times with pressure released between squeezes.

Thanks for sharing the link SPP, interesting read.

Then it is not a doubled die, in the established meaning of that word...

The coin is Machine Doubling, if it were a double die or even a regular strike for that matter than the devices would be of Norman(for standard) or wider(for a double die) the coin presented has thinner elements where doubling is shown which means that it is without a doubt a machine doubled coin!. The only way a doubled die can occur and have thinner devices is if the design/writing is incused which is not the case with this coin.

Here is a montage of Pierre V's picture and a regular 2014 quarter.
This is the best I came up. The red outline is that of the normal coin. I am convinced that the elements are not thinner but of the same size and thus a double die. Anyways, I will keep my eyes out for this one and report back with better pictures.

After just 20 rolls of circulated quarter, I found one.

Here are the pictures I have promised. Same magnification and lighting was used to obtain both images in the montage. The other pictures shows different sections around the coin.

Your verdict ...
