So my friends lid should be $2,5k Thats why I asked here as local khmers are trying to cheat out his winner for almost nothing.
Thank You for advise.

Sorry for picking up an old thread. I need an advice on the last picture here. Was it a some kind of winner? Friend of mine got similar one with number 10 on it. So far khmers are telling different stories - from 10k riels to 10 millions. Some try to exchange it for 20bucks. So what does it mean?
