Guilty as charged! I came into a number of decks recently and got a good price on that last pair. The top 3 bidders were over $200.
I can't add much info. Here's what I know without any reference material handy. The norms for the standard run of Bicycle cards were Ivory and Air-Cushion for a long time, though I've got Bicycle decks that omit the finish type on the box altogether. High Finish, like Ivory, are smooth.
At some unknown point with the most recent of US tax stamps until another unknown point with USPCC blue stamps, there were High Finish. I have only seen Bicycle High Finish in the simplest box style -- the box printing is red and blue with some gold borders, the 4 edges show their finish, 808, Made in U.S.A., and The U.S. Playing Card Co. I'm not aware of Ivory Finish nearly that modern. I do have a tax-stamped open pair of HF as well in the exact same box. That does some narrowing down, but not much.
Right now, there is an opened Bridge Size High Finish deck on eBay for around $90. Is there a tax stamp or other reason you'd say your deck is 1953? All the High Finish Bicycle (wide) decks I've come across have appeared to be right around the 1965 tax cutoff, possibly into 1973? Other brands show this finish earlier.
I, too, would like more information. My guess is you have a gem.
