A bit off subject but can anyone advise if money exchange like superrich take a British bank card as opposed to cash?

This is and everything else question. I move back to United States next week and I have this whole jar full of coins that I've been piling on to for the past year. How can I turn this in for cash? Do I just take a whole jar to the bank or is there a coin counting machine I could put this in?

Edit: so people can stop with the giving it away to charity post. My mom has terminal brain cancer and I'm going back to the states to help take care of her because she only has about 3 months left to live. I won't be working and will be around to help out with her hospice care.

Can anyone verify if Bangkok Bank at Chaengwattana is open? They were very efficient last year in preparing my bank letter/ statement. Would much rather use them than my local branch. Thanks

Any Western Union branches open these days?
