Help with Valuation - Good Condition Silver Coins (Early 60's-90's)

[Rangers09]

Hi All,

My father-in-law recently used some "quarantine time" to dig into my Grandfather-in-law's old safe (he unfortunately passed away in the early 2000's). Turns out he was a coin collector, and we are thinking about selling some of his old stuff. I've done some preliminary research, but wanted to get this board's opinion as well. I've glanced at eBay, but not sure how much condition factors into the appraisal?

What is the approximate value on some of these? I've got connections to a couple of pawn shops, but what is typically the best avenue for sales?

Various Quarters from 1959-1965 (Majority in similar condition as below) - I see these around $4 each on eBay:


Various Half-Dollars from 1961-1965 (Majority in similar condition as below) - I see these around $7 on eBay:


Early 90's Walking Liberty Silver Dollars (Very Good Condition) - I see these around $20-$23 on eBay:



Late 80's Canadian $5 Coins (Condition varies) - Seen these up to $20 each on eBay:


Thanks for any help!!!
