Headlessone, looking at a horizontal roll from left to right, you could get HH, HT, TH, TT. So the one head one tail pattern is more likely. It seems most people are okay with all tails or one head, one tail, but do not want all heads.
So let us examine the one head - one tail scenario. Although it is the most likely, for it to occur over even five rolls is .5 x.5 x.5 x.5 x.5 = .031 or 3% or 1 in 32. Over 12 rolls the odds of one head one tail showing on each roll is 1 in 4,096. Almost impossible. It is like tossing 12 coins at once and getting all heads. Try that 20 times and I bet you will not even be close to getting it. Just for fun, I went to the bank today and asked for 12 rolls of dimes. When I got home I checked the ends of the rolls and had only 5 rolls with a head/tail combination.
My calculations assume that you have an equal chance of a head or tail at each end. If they are wrapped randomly that is the case. But maybe they are produced and packed in a way that more heads are shown or are hidden much of the time. That I would not know. I have to assume that heads and tail are equally likely to be showing.

Here is something to think about... I recently opened and viewed 20 packs of the Stanley Cup 125th Coin packs. 2 packs came in each little folder and every folder opened, revealed all the coins Reverse up showing the Stanley Cup. Just something to think about.

A smart gambler many years ago asked me in Vegas, what's the next roll of a roulette if 16 black # were rolled, I foolishly answered red, he said no dummy the true odds are always same 1 in 38 and the ball is blind. Now most collectors who paid a premium for these rolls are not gamblers hoping for a head tail roll just kind of expected it, and inferred by the RCM ad, but the odds should be same for head to head, tail to tail and the head tail percent whatever that is.

Though I appreciate your 'odds' John100, The issue is only about 1/2 of not getting Head/tail rolls...only because it appears that this is the first time it has been an issue where MANY rolls are not the desired configuration vs as an example was give of 10 rolls of last pennies where all but one was H&T..the last being reverse both sides. So, what changed. Do they just not give a $hit this time round?

I am almost sure these and all recent rolls at Winnipeg is done randomly, the big difference with the penny rolls were they instantly for what ever reasons went to crazy prices instantly, nobody cares, but theses sets are marketed differently and seems most collectors cares, and you are correct the RCM does not care, but might change their views on these or future special rolls hopefully.

I've never understood collecting rolls. I prefer to be able to see and enjoy both sides of my coins.

Kind of boring last night then open up all my cases and rearrange my special wrap rolls. ( bought My Canada My Inspiration Wrap Rolls from dealer with discount but no return allowed because of HH rolls )
Now I got 4 cases with all HH rolls and 5 cases with all HO rolls. ( still need to figure out what to do with rest of other rolls, some OO, some HO, some colour. )

Who wouldn't want a roll of uncirculated coins fresh from the Mint untouched by human hands. You may get a MS65 or better coin from the roll. What I can't understand is why are people paying $90 on top of the face value of the coins for a "special wrap" piece of paper. The face value of the coins is $95, yet the RCM is charging extra $90 for paper and a cheap box. There is absolutely no difference between the special wrap roll coins and the cellophane wrap roll coins. If you cracked them both open you will find the same uncirculated coin. With some luck you can find the cellophane wrapped rolls for face value at banks.

tried that Moneypenny, but it seems none have them in my area. Quite frankly, not running around for a day and a half is worth the $90 to me.

Colonial Acres has the cellophane wrapped rolls for a modest premium over issue price. https://www.colonialacres.com/category-s/1050.htmDoes not include the GITD or coloured quarter. Your local coin shop may also have them. Banks may have them later in the year.

Thanks for your reply, punman. So it sounds like the random average should be something like 2:1 favouring the HT roll. Apologies in advance if I have misunderstood your point. That said, it sounds like your dime venture approximates the expected outcome. Now, that same expected outcome holds good for me in my experience with stock mint rolls if cup quarters, but not the special wraps. In the wraps case, the ratio is approximately flipped around 180 against. I have more than a large enough sample if your hypothetical is correct. Interestingly, in the case of the special wrap half dollars the ratio is 1:0. (if that is even a thing!) Every roll is HT.

Banks may have them later in the year. Cellophane wrapped rolls total $130.75 (VIP price). Unique 150th Special wrap roll set at $179 has (supposedly) 1/3 GITD toonies and 1/3 coloured quarters, and is nicely displayed in a case. To me it's worth an extra $48.25, especially since collectors are paying $8 to $12 for the GITD toonies. LCC selling them for $8.00. Will check local banks later, but not expecting to find any in my area.

So, back to this topic. I received another 4 rolls of fifty cent pieces, and the final configurations are, including my first rolls received: Classic: HH, HH, TT Special: TT, HH, HT
So, my question is, Should I keep the only roll that is Head/Tail, and a Tail/Tail from the classic? or, should they match, and have two rolls, both tails/tails?
I am only doing this once, so, there is no turning back after I return 4 rolls.
Oh, and by the way, I went back to all my collections of rolls, including special rolls, and my olympic set, and only one was tail tails. All the others are Heads/tails. This can not be a coincidence that I was that lucky considering this 50C fiasco.

Personally, I'd keep the tail/tail for both Classic and Special rolls, but that's just me. I don't need to see the Queen's face on every coin.
I ended up with tail/tail for each roll in the 150 Special Wrap set, except for the 5 cent roll, which is head/tail.
