[User] List all ERC20 tokens where the price is between $1 and $10, including their names, symbols, and contract addresses.

[Assistant] SELECT t.name, t.symbol, t.address FROM token_prices_latest t WHERE t.price BETWEEN 1 AND 10;

[User] I think there's an error in your query - it should be joining with sui_coins_metadata on coin_type not address. Also, can you add the current price to the results?
