If your asking the value of the coin then you'd generally talk collectors value also the silver content in your coin. your coin is a little bit smaller than a ike dollar and your coin has less silver than a morgan and compared to a Benjamin Franklin half which has 90% silver same with 1964 Kennedy half and 1965 to 1971 Kennedy dollars are 40% silver but yours has .835% silver according to Google making it more than a Benjamin Franklin for spot but less than a morgan dollar. for collectors value that's a whole new story. As for the 5 franc is equivalent to $5.39 and compared to a half dollar that'd be $4.89 more than a half dollar in face but your coin is worth more than that in silver and I'm to tired to do math on a weekend so I hope this helps no shame to being new and reddit is a little unforgiving and it kinda discourages new collectors kinda sad but is the truth happy collecting:)
