It's really not worth wasting much time on this. In thirty years coming and going to Thailand I have never been questioned about currency, nor even stopped on entry for any reason. Nor I suspect has almost anybody.

If your that worried you can post or transfer to me pm me for my account and address details reo reo.

I think that Mattd is correct. Customs "might" try to claim that you couldn't bring B60,000 into Thailand legally if you hadn't taken it out of the country illegally. But as long as you have 2 or more exit stamps from Thailand, you can claim that it is a total amount from 2 or more earlier trips, and you should be fine. You could also claim that part of the Baht that you are bringing back Baht into Thailand is to help a friend who had more than B10,000 from an earlier trip. Either way, you have very little if anything to be concerned about bringing B60,000 into Thailand. 

He would not have to explain why he took out 60,000 baht from Thailand from previous trip as there is no limit on amount of Thai baht brought "into" the country. He could have bought Thai baht in US  from a bank to satisfy the 20,000 baht or equivalent in US dollars when entering on visa exempt or a TV.

Last time when I left Thailand I had around 60K baht (Thai currency) with me.

To my knowledge, there are no restrictions in bringing Thai baht into Thailand, however there is an upper limit on cash in total, which used to be equivalent to $20,000, but believe it's raised now to $50,000. However, you are not allowed to take more than 50,000 baht out of Thailand in cash – I think the limit is even 100,000 baht for a family – so next time, it's probably not a good idea to bring 60,000 baht home...

For future reference, since the OP is talking about Thai-US travel, I believe that entering the US, if you have more than $10,000 equivalent in cash (all currencies combined) then you must declare it on the customs form (and probably go through the red line). Less than that you have nothing to do or worry about. I'm not sure what the rules are for leaving the US, but due to anti-money-laundering rules, I would check up on it if I needed to carry out more than $10,000 because I suspect the limit might apply in either direction.

 

But I agree, 60kB is not an unusual amount of money to be carrying through. Just don't put it in checked bags unless you're trying to tip the baggage handlers excessively.
