Numismatic Toonies - All Bimetallic?

Are we being facetious here?

Sure if you mean a toonie on a loonie, on a nickel planchet or toonies on foreign planchets

Thank you for the clarification, loonietoons.

It appears that by "numismatic" you mean NCLT (non-circulating legal tender).

There were many [EDIT: Canadian] NCLT coins denominated 2 dollars, and some of them were in fact monometallic (usually silver), such as the entire silver part of the Animal Portrait series.

Silver versions of various circulating toonies were apparently traditionally made in selectively gold-plated silver, which might not quite qualify as monometallic, but at least one recent issue was in fact made entirely in silver with no plating. [EDIT: different size, though.]
[EDIT 2: and also minted in Winnipeg - not sure if that disqualifies it?]

There is a 2004 Canada sterling silver proof two dollar polar bear coin called "The Proud Polar Bear" from a RCM coin & stamp set. Don't know if it could be considered a toonie, but I have included it in my proof toonie collection and it is the same size as the other toonies.


As well there is the 2023 2 dollar (toonie), composition .9999 silver, weight 31.39 g, diameter 38 mm (the "regular" toonie is about 28 mm). specimen finish and the "W" mint mark of the Winnipeg Mint.

Silver Toonies in the Silver NCLT sets they aren't bi-metallic.
Silver $2 coins that belong to variety of Silver fractional sets (Maple Leaf, Arctic Fox, Lynx).
Silver Bullion 3/4oz coins have $2 face value.

I have wondered on those modern silver sets, though. Are they really two pieces of silver with a gold-plated core (bimetallic style, but just one metal)? Or are they solid silver pieces with gold plating only where the core would be. I don't imagine the mint expects anyone to destroy one to find out, nor have I heard of anyone doing so.

My understanding is that they are a one-piece planchet with selective gold plating.
