Anybody else find original register receipts in their Gold or Silver Age comics?

So I was paging through my copy of 80 Page Giant #15 and I found the original Thrifty Drug register receipt from 1965. Seems like this would be a common occurance, but I don't think I've ever heard of a Golden Age or Silver Age book with the original receipt inside. I wonder how CGC would handle it if I submitted the book. Would they throw away the receipt along with the mylar when it first arrived there, or would they keep it in and note it on the label? Anyway, it was fun to see where the book was purchased and on what day, especially since it was within a couple of weeks of the day that I was born!

Cgc will not slab loose items like the receipt. They may return the receipt in an envelope but will keep the used mylar.
