Legacy Of The Penny Five-Coin Set

I'm not suggesting that the mint should still be making pennies for circulation. There are tons available at dealers but none dated beyond 2012. These were available at face value from banks as they were introduced into circulation.
According the the RCM, the cost of producing the penny is 1.6 cents so clearly that would be a bad idea to keep making them for circulation. However, it the RCM issues 5 coin sets made of silver, I don't see why they wouldn't approve 50 made of copper. If the mint rolled them with a similar style to the farewell rolls, and sold them for the same price as the farewell rolls, they would make a huge profit.
It would cost 80 cents plus the cost of the roll, (they already have machinery for packaging), and would sell for $10.
Those that collect pennies could continue to for 20 cents each coin, 50 at a time. If they limited the mintage to 5000-7500 rolls, I could see a strong market for them. Some people might crack them open to search for high grades to get slabbed, while others would leave them intact. Either way, it'd be a profitable way for the mint to get a younger crowd into the hobby. $10 for 50 coins sure beats $710 for 5 in the eyes of a 10 year old.
At 10 bucks, I'd get a couple rolls of them just so I can continue to give people my 2 cents.

What about a few coins that are gold plated and silver plated put in random rolls? That would make many people break them open to search and would increase the resale value of the rolls as more get opened. Like a coin lotto. Maybe put 100 silver plated and 50 gold plated.
That would sell out for sure. The possibility to get a 1 cent coin with a mintage of 50 would be a cool, especially at $10.

Although the 50 cent coin was not formally removed from circulation the same way the penny was, I don't know of any place to get 50 cent coins at face value. I'd call it a NCLT.
I don't see how selling rolls of pennies would be any different.
Not all coins come with COAs. The date would suffice. Anyone who counterfeits a Canada copper penny is giving the government money.

Penny profits
Better keep your day jobs if you hope to make any great gains from flipping this set or 99% of NCLT - especially with so many new coins each month...despite low mintages.
It's now all about collecting for the joy of it as it should be.

When the market will be destroyed "enough", will be no single coin, that you wouldn't be able to get for discount later

Try Cdn Coins and Currency. It's still available at issue price to VIP members, not sold out yet. They're generally very accommodating.

Too bad the RCM did not stay true to the original design of the first three coins. The numbers are spelled out on these originals, and look much nicer, imo. This set would be more historically significant if they hadn't made the change.

Compare these original one cent images to the 2017 Penny Set:

Still a beautiful set, though.
