Categorizing The Rarest And Most Expensive Canadian Coins

Re the 59's

I've moved past their existence and now would like to know the story behind the composition if that's possible. Given that all your samples have fallen into a grouped tolerance I'm not sure if simple metal segregation is the cause their for existence. Not that I can prove otherwise, of course but -

I have theorized that if it were just segregation we would see both tin rich and zinc rich stratification in those ingots and possibly some other material that caused this blatant macrosegregation (maybe a little Fe or Si). Further, I'm thinking this kind of segregation would show defects in the extruded material that would carry over in the planchets. Just a thought.

If you're working on this, I'm looking forward to seeing it. A lot.

The 2000P 10, 25 and 50 cents where made for the vending machine industry (all where minted in Winnipeg) and some ''escaped''. The 1921's (5 and 50 cents) where released and that is why you find most of them in good to very good condition with none known in VF or EF and only one in Fine. 3 are known in AU and ICCS has 4 in mint states one that used to be a 65 and now is a 66 so in reality only graded 3 in mint state one in 64, one in 65 and one in 66. PCGS has graded one in MS-67 that now resides in a permanent collection that will be donated to the currency museum so a 66 is now the highest available. I also like the 1889 and 1893 round top 3 10 cents. The 36 dots where probably inside jobs some say for Pittman and that is why a lot of people are no interested in these coins. Specialty collectors go after the 36 dot coins.

You forgot the 1916C sovereign (about 50 known), the 1870H 10 cents mule (2 known) and the 1670 5 sols and 15 sols. I have only ever seen 1 15 sol (less than 10 known I think there are 8 known but they never show up for sale) ever sell and it was in 1997 threw a signature auction in the U.S.A for over 200 000$ the currency museum in Ottawa has 2. I also like the 1870 no LCW and 1890H 50 cent pieces. Love the one that sold in Heritage in January of 2010 as part of the Canadiana collection (1890H in PCGS MS-64 just a stoning coin).

Ugly, funny you should mention segregation of Sn and Zn, and other oddities like Fe.... (perhaps even Pb)...

:)

oh OH OH that is so NOT fair... I feel like I'm ten and I've been teased with a hint about my birthday gift.

I shall wait.

Did you say SEM? That would show the defects caused by segregation (if that's what it is) and more... I would like to see to see those scans or at least the results very much.

You folks out there holding these expensive pennies... temporarily donate your cents to the cause, they won't be harmed.

danlos,I like your system
in category 1 I think that Matrix has made an unassailable case for moving the 21's down to category 2,and I believe in all likelyhood someone such as SPP will have proof the '59 brass should move down a category as well
for category 2 I don't think you'll ever get consensus for a complete list there,same goes for category 4
category#3,a mules a mule
I actively seek coins from category 2&3,
fortunately I don't consider category 1 important because I could never afford a coin listed there
I don't actively seek category 4 coins,but somehow I have 9 of those you have listedserendipity?

I know... the list was not meant to be exhaustive...:)

I thought the 1944 Tombac was an accidental 1943 planchet in the 1944 hopper. I don't think it was ever intended to be struck. That would explain why only one very circulated example is known.
