Hello everyone.
I recently started working part time in a car wash. One of my co-workers is quite the character and helps the time pass. Every day I am regaled about how the moon is a spaceship, humans used to be 12 feet tall and other various stories.
One story I hear about once a week is Wade's amazing twoonie. It has to be worth at least a $1000, he says. I always ask to see it and he always says "I will dig it out some day".
The story changes a bit every time he tells it but the constant bits are as followed

I found it in the grass when twoonies first came out (I am assuming 1996)

It has 12 sides (although once or twice it had 8 sides)

They forgot to put the gold part in it (I assume it would be an all silver colourd alloy)

I had a friend look it up on his computer thing and he says it is worth a $1000. To me it is priceless but I would sell it for that, anything less than that and I would keep it as it means more than a grand to me.
I can not find any record of what he is describing being sold at any auctions. With out an auction sale I don't know how he would get that price.
I have heard of Canadian coins being struck on Israeli platchets before so I started looking up foreign coins that could host this error. I found unsourced information about a 1996 twoonie being struck on a 1996 Bangladesh 5 taka.

Could this be it?
Again, I invited him to coin shows to have it looked at and it was a no go. Today when we were talking about it he said he doesn't keep it at home and he will dig it out and he may sell it to me if I have a grand.
He also said he wrapped it in paper towel and it scratched it a bit.
I don't know why I believe him but I do. Everyone else ridicules him about it but I think he may have a real winner here. He keeps a copy of Krause and the Bible under the work bench at all times so I know he is actively looking for coins.
Has anyone seen what he is describing? Can anyone give ma an idea of value?
