New Thai Coin: 2 Baht

Last week I took a bus, I got 2 baht coin, light brass color, from a bus boy.
"What's this? Why is this color? Why is not silver color? I said to myself.
"It's new. Another color. It's not heavy and cheaper budjet to make it."
One young lady said to me.
"Really? I just knew it. It's nice color and it's easy to separate from 1 Baht coin." I said to her and didn't forget to say thank you to her.

When someone wants to know more about Thai language, he can read the article following:

"rian" (Down and up sound) means coin in English.
There are 6 types of coins in Thailand; they are 25 sa-dtaang and 50 sa-dtaang, golden color,
1 Baht, silver color, 2 Baht which has silver and light brass color, 5 Baht which is silver color.And 10 Baht coin which has silver and golden colorin 1 coin. The golden color is in the middle. Every coins have round shape; except, 5 Baht coin.
Therefore Thai people say: rian 25 (yee-sip-haa) sa-dtaang or 1 sa-lueng, rian 50 (haa sip) sa-dtaang, rian 1 (nueng) baat or rian baat, rian 5 baat and rian 10 baat.

"kor laek rian yoi noi?" means "May I exchange small coin, please?"
"laek" means "To exchange"
"rian yoi" means "Small coin"

PS:Interesting meaning of "yoi" which means to digest so after meal some Thai people like to say "doen len yoi aa-haan dee gwaa" (It's better to take a walk to digest.)
