Canadian 1978 Red River Indian Siver Dollar?

i have red river Indian dollars from 1978 :one is SGT TOMMY PRINCE , CHIEF GORDON lathlin and treaty number 6

ITS A KIND OF A LITTLE BOOKLET THAT SAYS:

THE GOAL OF THE 1978 ISSUE OF THE RED RIVER INDIAN DOLLARS IS TO RAISE

SUFFICIENT FUNDS TO INSURE THE COMPLETE RESTORATIONOF THIS MOST SINIFICANT RELIC OF THE RED RIVER SETTLEMENT. there's more explication

than that i just put the main one. the booklet in a plastic cover with strong carboard with the dollars fitting in.

i would like to know the value of these peaces in Canadian dollars.

thank you in advance for your answer.
