This is a Scott #PR125 Newspaper & Periodical stamp from the late 19th C. I've explained how these were used in another post here on StampExchange. The stamp itself is unremarkable - it catalogues for $65.00 but I bought this one for $7.50 because of a nasty thin. Without the thin, it might go for all of $20.00 as it is nicely centered and the colour is somewhat brighter than here appears. (En Passant, there must still be quite a few collectors of N & Ps as the bidding on most items is quite robust on eBay.) But it got me to thinking (which is often dangerous!) about the value of $100.00 then-and-now. The best calculation I have is that $100.00 in 1895 would be just shy of $3000.00 today, anno domini 2018. I purchase and sell a lot of books, so I know $3000.00 media mail would ship quite a few boxes of books! I wonder how many newspapers this $100 stamp would have mailed back in 1895?
