Proof, Specimen, Proof-Like & BU: Coin Finishes Explained
Two coins can have the same design, same year and same silver, and still look totally different. The difference is the finish: how the Mint prepares the dies and strikes the coin. Here's what each finish means, how to tell them apart and where you'll see them in our shop.
Brilliant Uncirculated (BU)
The Royal Canadian Mint calls this its basic finish, the one used on most of Canada's everyday coins. On a BU coin, the design and the background are both shiny. No mirror, no frost, just a clean, bright coin that was never spent.
Specimen
Specimen coins are a step up from uncirculated. The Mint describes the finish as precisely machined lines in the background with a highly detailed finish on the design. Tilt one under a light and you'll see a soft, lined satin background behind a crisp design.
You'll see the specimen finish on the cased commemorative silver dollars of the 1970s.
Proof
Proof is the showpiece finish. The background gets a mirror-like polish, so the fields of the coin shine like glass. The design itself is often frosted, which makes it pop against the mirror. That contrast is what collectors mean by "cameo."
Most of the modern Royal Canadian Mint coins in our shop are proofs, from 1 oz fine silver coins to big 2 oz and 5 oz issues. Heads up: that mirror background shows every touch, so proofs are the coins to be most careful with.
Reverse proof
Flip the proof idea around. On a reverse proof, the background is matte and the design shines with a glass-like polish. It pulls your eye straight to the subject. Our 2012 Welcome to the World: Baby Feet coin is a reverse proof.
Matte proof
A matte proof is like a standard proof, but with a satin background instead of a high-shine mirror. It gives a coin a softer, older look.
Proof-like (PL)
Here's the tricky one. "Proof-like" isn't an official Mint finish. Starting in 1953, the Mint sold sets it called uncirculated sets. The coins were struck with more care than regular pocket change, and many came out with flashy, mirror-ish surfaces. Collectors started calling them "prooflike," and the name stuck.
So a proof-like coin looks sharp and shiny, but it isn't a true proof. Canadian PL sets from the silver years (up to 1967) are a favourite with collectors of classic Canadian coins.

Extras you'll see on modern Mint coins
On top of the finish, a lot of modern Royal Canadian Mint coins add special touches: selective colour, holograms, Swarovski crystals, gold plating and even glow-in-the-dark ink. We've pulled the best of them together in Hologram, Crystal & Glow-in-the-Dark Coins and Coloured Silver Coins.
FAQ
Is proof better than specimen?
Grading companies rank specimen above regular coins and below proofs. "Better" is up to you, though. Plenty of collectors love the satin look of a specimen.
Is a proof-like coin a proof?
No. Proof-like coins were struck with extra care and can look mirror-like, but they're not true proofs.
Why do proofs show scratches so easily?
That mirror background shows everything, even tiny hairlines from handling. Always hold proofs by the edges and keep them in their capsules.
How do I know which finish a coin has?
Every one of our listings names the finish. If we haven't confirmed it yet, the listing says so.
