NCLT Coins Are Not Legal Tender, Including The $20 For $20

I buy one of each $X for $X coin for my personal collection, as well as a few extras sometimes as gifts. I look at it as a $20 gift that will be worth $20 no matter what... To me at least. I've had no trouble selling a few on a local buy and sell website, traded them for other stuff, and have used them at face value at coin shops. I've given a few to my nephew and told him he could give them to me at any time, and I'd give him a few bills instead. He's 15 years old and has hung on to them for several years now.
These are coins that start new collectors in the hobby as well as give collectors with a very limited budget the ability to grab a few coins here and there.
These are unlike other coins made by RCM, and even if you can't use them to buy smokes at 7/11 or fill your car with gas, I can't see them selling for less than face value. Especially if the series continues for many more years. New collectors will gladly spend a few bucks over FV to complete the set 5 years from now. In fact, I paid $30 to get the first coin in the series. It may seem silly to big time spenders of RCM NCLT products to buy coins with such a high mintage, but I believe they hold their value better than 99% of new products.
With lots of new coins being pumped out by the mint, this series has to be the best bargain. And are basically the only NCLT coins I will be buying from now on unless something really cool, like a picture of my face appears on the next months release. Any sets I care to complete will be done on the secondary market, from brick and mortar stores in an attempt to keep them afloat. Many of us have spent $100's or $1000's+ on coins that will never be worth what we paid for them. I believe these will. Perhaps not at a bank but collectors will pay FV all day.
If you want to spend them, give them as tips at your next dinner out. Use them as poker chips. Drill a hole and make a necklace, (or see if they fit into the one the mint sells).
To anyone that says they are only worth melt, I say "how many ya got?" Followed by "I'll take them all."

Does the Bank of Canada redeem $20 for $20's?
If they don't, they are in a practical sense not NCLT.

The Reserve Bank of Australia is required by Law to redeem all Australian NCLT as face value.

A few pages back, ShareBear referenced a related CCF thread where the UK banks stopped accepting NCLT at face value, because at least one UK Mint customer was using his credit card to earn perks (flight miles, product discounts, cash back, etc.) and then taking the coin purchases to the bank to redeem for cash. Here's the thread, which contains a link to the news article:

Consequently, if someone tried this "free credit card perks" scheme with Canada's x-for-x coins, he/she might have trouble finding a bank to accept all the NCLT coins. Maybe too much of a risk in Canada, especially on large credit card purchases, like for $200-for-$200 coins?

http://laws-lois.justice.gc.ca/PDF/R-9.pdf - The Royal Canadian Mint Act (R-9).
Have a look at the section Schedule. The section lists the denominations of NCLT and give specifications on circulating legal tender. For example:
5 A ten cent coin of which
(a) the composition is pure nickel;
(b) the standard weight is 2.07 grams; and
(c) the margin of tolerance with respect to weight is
21.44 grams per kilogram of 483 pieces.
5.1 A ten cent coin of which
(a) the composition is nickel, copper and nickel-plated steel;
(b) the standard weight is 1.75 grams; and
(c) the margin of tolerance with respect to the weight is
±34.43 grams per kilogram of 571 pieces.

Therefore silver dimes (pre-1968, including .500 1968 dime) are not legal tender. Also according to the act, silver nickels (pre-1922), silver quarters, silver 50 cent pieces, silver dollars, nickel dollars, small cents from 1920-1981, and large cents are not legal tender.

Read the Currency Act.

As far as I know, no Canadian issued coin has been demonetized. They are all legal tender.

The purpose of the Royal Canadian Mint Act is to regulates what can be minted by RCM going forward, the perimeters of new coinage per say. It has nothing to do with deeming whether old silver dimes are still legal tender or not. If you dig through Bank of Canada legislation, you'll find indeed they are still legal tender. It's BofC that carries the responsibility of coin and currency nationally, not RCM.

Adding: this is regarding legal tender:

If any of you have spare face value coins (i.e. $20 for $20, $100 for $100 etc.) and your bank doesn't want to cash them for you, you may want to contact these dealers:
http://wsdcoins.com/store/
http://www.thecoinshoppe.ca/
They will accept these coins as payment at their face value for goods purchased in their store. But contact them first to see if they still offer this service.
Both carry bullion as well, which I think has a better chance of appreciation in the long run.
I can personally vouch for the first dealer, WSD Coins. And not, it's not me! ;)

Now with a limit per household this problem should be somewhat under control...
