Sorry, not an error, it is just PMD. Value 25 cents.
There is nothing there that could happen during the striking of the coin.

A DIE chip is not an error, it is part of the minting process.
They are quite common especially in since1947 when they started using chrome plating on the dies.
No numismatic value but hold onto it if you like as an example.

A test note is exactly what it says. The BOC was wanting to try out things such as better inks, different types of paper etc. to see if they could improve the quality of the notes. They were then issued to the public to check for durability. Some of these are rare but in your case there were 600,000...

According to the Charlton catalogue, the range for B/M replacement notes are
0000001-1159710 and 1761631-4300666 for a total of3698751 so you are in that range.

Looks like an overpolished die. P

What is it you are referring to as die damage?
Please be specific so we aren’t both looking at different things.

Congrats on selling all of your Morgan’s. There were some good deals there.

Welcome to the Forum
As TBH stated, it is a common series with over 90 million printed so there is no value unless in CUNC condition.

Not an error, deliberate damage. Someone just getting creative.
Value 25 cents.

Which mint marks

There are no mint marks Bill, they were struck at the Philadelphia mint.

I agree, worn and polished. Would probably grade as a details coin.
Don’t know how anyone with grading knowledge could say that is BU.
Of course selling it would depend on what you are asking for it.

I don’t know of a website but there is a catalogue that has all the info you need.
“Canadian Government Paper Money” by Charlton. There is also lots of other info
included that may help.

Could be struck through grease.
Not uncommon and adds no value.

Thanks for the second picture, now we can identify the error. As Bill stated, it is an off centre strike.
Errors are hard to evaluate as everyone is different but I would guess it may be worth about $10.00.

Please show a photo of the reverse so we know which error it is. This should always be done with every listing.
Also banknotes are printed, coins are struck.
