Baht Coin

How do you tell the difference in Thailand coins?!?
I found a coin that looked like a quarter on the ground when I picked it up I realized it’s not american at all. It has a face on the front and two elephants on the back with trees that look like pine trees over the elephants. I looked it up online and it looks like the 1 satang 5 satang 10 satang and 1 baht coin on this website http://www.msymboll.totalh.com/asia_thai_baht_coins.htm . But I have no idea which one it is…. I’m just kinda interested… also does anyone know what it’s worth?
These are coins currently used in Thailand.
