The current 78 year old designs are showing their ages. I wish the mint would commission a redesign of all of them (especially their sizes; a one dollar coin should be no larger than a nickel) and then stick with them.
Do not get me started... My problems with the current coins are:
1. The "US" denominations: 25 cents, rather than 20 cents and no 50 cents.
2. The 5 cent coin is the same color and almost the same size as 25 cents (again, same problem as in the US).
3. 5 cents, $1 and $2 coins are too large.
4. Outdated designs. The denomination numerals are too small. One needs to know the designs and sizes to recognize the coins, which is a problem for visitors to Canada.
5. The commemorative coin designs are poor and often too busy to be recognizable.
