I’ll take it to the bank tomorrow. It’s never been raided for quarters. About 6 inches across. Could be $30-$60 in my estimation.
Closest guess gets a reply.
EDIT: It was $79.85
$45 in quarters, $18.60 in dimes, $8.10 in nickles, and $8.15 in pennies.
Worth is largely contextual no? eg, if you’re offering it to a drowning man, that jar is worth less than nothing.
But hopefully that jar had good parents that built up its esteem, so that in any context it has the greatest gift of all: self-worth.
