Seems very fair Rog. You might have to bid up to $5 in an eBay auction but your price at an antique shop is excellent. The Las Vegas pair is noteworthy in the day/night aspect of the same perspective. The Reno sign is still spanning a Reno street today, just exit the Siena at the valet exit and there it is, Lake Street I believe. I too await Jody's lesson on the detection of repo postcards.
Never worry too much about what you pay for casino collectables if you like the item. I think I've paid better than $20 for pc's I knew to be rare and would be a killer enhancement to my chips. You'll get the "eye" after a few years, meanwhile enjoy!
