Silver coins 1968 Canadian Quarters and dimes

These are a lot 1968 quarters and 67 and 68 dimes. This coins have 50% silver content. As can been seen on the scale, their weight is 130 + grams meaning there is 65 grams of silver in them. At today's price per gram ($3 Cdn) the total value is approximately $195. This price fluctuates a lot recently with $2.60 being the bottom end and $3.85 at the top. I am asking $160 for this lot of vintage Silver Canadian coins. Porch Pickup only. Pape and Danforth Area, Muriel Ave. East York.
