I have been thinking of getting at least two SLQs as memorials of my parents — 1920 and 1924 dates. Just taking a quick look at slabbed examples of these two years on ebay, I've come to the conclusion that there's not much reason to the pricing on them. I've seen them priced as high as more than $10,000 and as low as $75 for very nice looking ones. In fact, one just closed for under $70 without a buyer. I'd be grateful to those in the know to give me advice on these two years in particular. What's a fair price to pay for one that at least approaches a higher grade? If there are years (other than 1916) that are the real rare ones, I'd like to know that too in the event that I might decide to go beyond the '20 and '24 issues. Thanks.
