I don't know that much about Canadian mint packaging, but I was wondering if they used PVC in them in 1966. If so, should I remove them and put them in flips or would it hit their premiums if any? Regardless, I want to preserve them as best as possible. As you can see, the mint packaging is not in the best condition.
IMH, the coins were wrapped nearly 46 years ago and look in great condition the way they are. That said, I don't like that style of wrapping in general. I guess the only way to have them maintain their "mint" status though would be to send them to PCGS for grading as is and let PCGS slab em for you. I'd do it for that 50c piece... I think the details in that coin are gorgeous.
No PVC, just mylar (like 2X2's, but thicker. They called the material something else, but no corrosion starters, unless there is a rip or tear somewhere so air can get in.
I don't believe these contain PVC. A quick, and sometimes incorrect, way of determining PVC is to smell the package and if it smells lightly like a shower curtain then there is PVC present. These are great designs and if you don't like them in the packaging then you have many options including cardboard-mylar 2x2 holders and the plastic, snap together individual holders. I adore Canadian coinage.
I also adore Canadian coins. There's a mint that treats a collector right There is a little rip in the corner that someone tried to fix with a strip of tape. Was thinking of getting them slabbed, but don't think the coins are worth the price. Maybe the 50c and $1 are but would like to keep them in a set.
My opinion is that you would be throwing money away to have them certified when there are so many other options available.
Maybe I'll put them in one of those "date set" slabs. I did that for my dads birthday a few years ago with all the US coins of his birth.
1966 they still made some of there coins out of silver.As of right now the Dollar,Half Dollar,Quarter and Dime are about $37 in silver.Being in mint condition could make them worth more
