It's hard to tell from the photos because I couldn't expand them. There are Arnprior dollars for each of those dates, but you have to see the waterlines in front of the canoe clearly. A normal coin will have 4 full waterlines; the "short waterline" type has 3 or 4 short waterlines, and the Arnprior will have 1 1/2 waterlines. If they are normal coins, each dollar value of any combination of Canadian silver coins from 1920 to 1967 is .600 troy ounces of silver, so each dollar value is worth .6 X the current silver value (at $25/troy oz, each dollar is worth $15, minus 10-20% for coin wear, as scrap) The short waterlines are worth a small premium while the Arnprior dollars are worth about a 5X premium
