A little treasure from under the behind

No , no. There's nothing obscene about this post.
I was going through the contents of my wallet today (that i usually keep in the hind-pocket) and discovered a rather curious looking coin. A closer look revealed that it was a dollar coin - but it did not look familiar.
It turned out that i had a Sacagawea commemorative golden dollar (2000 issue) in my possession. It looks like this :
Made me think of that trip to the New England area taken on the memorial day weekend. The trip was a mad dash between Keene in New Hampshire, Colchester in Connecticut and Boston.
I faintly recall that i had picked up this coin from a Trader Joe's somewhere between Boston airport and Keene, or was it somewhere else during the 600 mile stretch. I can't recall at all now.
But i did look up the U.S. mint site and read that the coin has a bit of history attached to it. A bit about Sacagawea being the shoshone Indian guide to lewis and clark on their expidition to the West of the United States.
Further, there is another interesting article that talks about the 'real' sacagawea - and also that the image on the coin is not the real sacagawea. (The US Mint site, has a section on how they finalized the design of the coin).
Quite a bit of education for one evening of cleaning my wallet.
Now, what do i do about the 1984 canadian cent?
