So, I got invited to a home game by some friends who haven't thrown a game in awhile, or at least haven't invited me to one in awhile. I asked if I should bring chips, plastic cards, chairs, etc.
"I think matt bought some chips. We don't have plastic cards though, and maybe you can bring a couple chairs just in case."
I brought my 500 nevada jacks set with plastic cards.
Another friend had brought his chips and he thought that I had the same kind because the aluminum case looked alike.

He opened his up and inside were 500 dice chips of 5 different denoms.
Matt opened his vinyl case and he had 500 dice chips too, in the same denoms. The chips are of two different manufacturer's, so they're different thicknesses, but they were set on using them. They were going to combine them and then use some of mine if they needed.
I showed them the ceramics, and they'd never heard of them. "You mean clay?"
They wanted to do $0.10/$0.25 blinds and my set is for a T1500 tourney or a $0.05/$0.10 cash game if you pretend the dollars are pennies. I convinced them to use just my set, since I had more of only 3 denoms, and we pretended that the nickels were dimes.
Got many "these are nice chips", and one person asked me how much they weighed. I said, "Almost 10 grams." I knew why they asked, but wasn't going to try to explain.
They were set on using their paper cards though. Which was fine with me. It was a new deck.
