cuds on Canadian coins

This is an 1859 cent that I think should qualify as a retained cud. Here is a photo of part of the reverse from leaves 13-16. It is a late state Haxby PC59-77a1.

There is a lot of lateral displacement at the leaf 16 side of the retained cud.

with Hounddog here... retained broken die is what I would call that one.

Yep, that would be considered a Retained Cud, since there's some detail left and the piece hasn't completely broken away yet. Nice find and congratulations!

"Since I'm a U.S. collector of Canadian cents, I'm a little confused. I have to say that "retained broken die" actually sounds more accurate, since it is part of the die that is "retained" and the "cud" or "retained cud" is what appears on the coin as a result."

I would agree with this statement.
I have always believed that a cud is the result of a broken die and created when the coin is struck.
If the broken die is retained then there is no cud produced once the retained portion shifts enough and moves to a different level then the rest of the die then a cud will be produced.
To me the term retained cud doesn't make any sense and is misleading to what actually happens, you can retain a broken die in a position to create a cud or the piece can be dislodged completely and produce a cud but I would never call either a retained cud.
Just my opinion.

That's a nice one Dorado! It's a very late state of the I3 reverse die. Haxby die pair PC59-412.

Thanks for sharing it!
