I have had the same 3+6=9 Achromat for the past 15 years. It cost me $99. At the show they wanted $150. I had to pass on that.
I'll be at table 806 doing photography. Stop by and say hi. One other thing you might want to do is spend a little time at Heritage lot viewing. It's in a quiet room away from the bourse. You have to register with them, which you can do for free online and doesn't obligate to you to buy anything, ever. They have catalogs in the room, which you can take with you if you like. The coins that will be there are for this auction: 2026 January 14 - 17 FUN US Coins Signature® Auction #1390 Browse it online ahead of time and find stuff you'd like to see in person. They will let you look at anything you want, but the super-high value stuff might be at a separate table with more security guards. To save time, have a list of lots you want to see ready so that you can check them off on the "menu" they'll give you. They hand you a box of about 25-30 coins at a time. In addition to lot viewing, the auction companies (Heritage, Stack's, GreatCollections) tend to have some pretty amazing stuff on display at their tables.
