The 1936 bar is actually a die crack that joins the two lower bow's.
To be considered a bar, it must be strong, clear and touch the bows at both sides.
Yours would not be considered a bar as it only runs part way across and does not touch the left side bow.

Welcome to Coins and Canada
Did you have a question or were you just showing them to us.
I see you have the colourized raised 2 variety. There is a premium for it over the other two varieties.

Someone has removed and turned the inner core. Have seen this before numerous times.
It is impossible for the inner core to be struck upside down as the inner core and rim are struck at the
same time from a single die. Someone has also damaged the rim.

Would you please supply a clear picture of both sides.
Hard to give an answer without seeing the actual bill.
It could be genuine, it could be counterfeit.

The fact that it is a replacement note gives it some value over a regular note.
Hard to give a value when you only show one side but it does have some stains and fold marks.
Usually a collector would like these notes in at least CH UNC condition but it still might be worth $5-6.00

Not a weak strike, coin has been damaged after it was struck, known as PMD (Post Minting Damage)

Those percentages take in account the impurities in the Nickel. 99.9% has .1% impurities.
The 1983 has 1% or less impurities. It is the same with gold or silver bullion coins. They are always 99.99% pure.
You never see them stating 100% pure.

All the Nickel Dollars from 1968 to 1987 were 100% nickel.
As to the answer to your original question, I don't really know.

I thought that may be the set. That is an aftermarket set in a Capitol coin holder. There are some for sale on eBay in fact there is one with all 5 varieties. I don't believe they are PL Dollars but Business Strikes. If it was assembled by the RCM, it would have their logo on it somewhere. I have no...

I assume that you are talking about the Silver Dollar varieties (there are actually 5). Sounds to me like it may be an aftermarket set as I don't know of any variety set being released by the RCMs plus they did not use clear plastic cases back then. Pictures would be a great help to determine what y...

There are only two in Canada that I know of, BCS as mentioned and CCCS canadiancoincertificationservice.com in Quebec There is nothing out West.

Probably taken a hit that has slightly flattened it.
Pretty sure it didn't look like that when the coin was struck.

It is not unusual to have a gap between the outer ring and the core. There are some out there that have a gap large enough that you can see through it. These usually bring a premium.

Looks like a plating bubble trapped between the brass plating and core.

Agree with Bill
