Nice coins, but I'm certain these are not the only ones worth posting that you have found. Don't worry about how little or how common they are: share!
BTW, I can make out the upper portion of as the last number in your SLQ. Raised date was often worn off SLQ's dated before 1924, so this might be a 1918.
Close! Look up what a 1918/7 S is worth, then remember you have already found a similar coin.
