Changing old $100 bill in BKK?

I'm not American, so I rarely use Dollars, but I'm intrigued to know why banks and money changers in Thailand won't change old notes. That same thing doesn't apply to Pounds or Euros, as far as I'm aware (although the notes aren't dated), so what is it with US Dollars?

yes it does apply  to uk withdrawn banknotes as they cease to be legal tender. however they maintain their value indefinitely and can be exchanged, in the case of uk banknotes, by commercial banks (usually where you have an account) or by the bank of england.

Because the currency wholesalers they sell the cash to don't want them. All they can do is hold on to the old note and give it to someone who wants dollars and who isn't fussy.

 

The thing with currency exchange is that the margins are thin. It's all about volume. So converting good money into an old note that has to sit on the shelf makes no sense at all.

If you are into Game Theory, you can auction it off:

 

The setup involves an auctioneer who volunteers to auction off a dollar bill with the following rule: the bill goes to the winner; however, the second-highest bidder also loses the amount that they bid, making them the biggest loser in the auction. The winner can get a dollar for a mere 5 cents (the minimum bid), but only if no one else enters into the bidding war.

The game begins with one of the players bidding 5 cents, hoping to make a 95-cent profit. They can be outbid by another player bidding 10 cents, as a 90-cent profit is still desirable. Similarly, another bidder may bid 15 cents, making an 85-cent profit. Meanwhile, the second bidder may attempt to convert their loss of 10 cents into a gain of 80 cents by bidding 20 cents, and so on. Every player has a choice of either paying for nothing or bidding 5 cents more on the dollar. Any bid beyond the value of a dollar is a loss for all bidders alike.

A series of rational bids will reach and ultimately surpass one dollar as the bidders seek to minimize their losses. If the first bidder bids 95 cents, and the second bidder bids one dollar (for no net gain or loss), the first bidder stands to lose ninety five cents unless they bid $1.05, in which case they rationally bid more than the value of the item for sale (the dollar) in order to reduce their losses to only five cents.

Bidding continues with the second highest bidder always losing more than the highest bidder and therefore always trying to become the high bidder. Only the auctioneer gets to profit in the end.[1]
