It was surreal.
There was one kid in the neighborhood with a strategy guide who knew where to catch everything, and he was treated like some kind of sage. If you didn't know how to get something, you'd ask them in exchange for some kind of payment (usually gum or something, a couple quarters, or even a card if you weren't already friends (our guy liked those Topps cards)).
This was a BIG deal, since once you knew how to get something good, you became THE guy to go to if someone else wanted one. You had a child-like approximation of power.
If you wanted something that wasn't in your game, or if you didn't deal with the guide kid, you'd trade with someone. Usually someone you didn't even know, but either they were THE guy or you heard from a friend that they have one. From there you'd work out a "fair" trade.
He had something you wanted so the ball was in his court, and depending on what it was he might not be so reasonable. You'd offer something, they'd usually ask for more, and you'd sweeten the deal until they either relented or you told them to pound sand.
Evolution trades were mostly limited to friends, since no one wanted to risk the other guy running off with it. But the handful of times that actually happened, word spread and they were effectively blacklisted.
Trading for legends or starters was unheard of. At least in my neighborhood, you'd only exchange them for dex entries, and even then it was just the final stage.
Gold and Silver crashed the economy.
Once rare Pokémon and starters could just be bred infinitely, they lost a lot of value as long as your group had a Gen 1 game. Legends still retained their value up until the cloning glitch became widespread, and that's about when Pokémania died off in our neighborhood.
