If you Eurostar out from schengen to the UK, you pass through schengen exit check, then a few yards later Uk entry check. I assume that Americans get exit stamps at the first check. Most countries that stamp passports give entry and exit stamps, whether you have a visa or not. More and more counties rely on computers to keep track of you though - Israel used to stamp you at Tel Aviv, now you get a piece of paper that you return on exit (you still et stamped at Erez when going in/out of Gaza). In 2015 Australia stamped when you use the manual system, but not the automatic system. I don't recall if the US stamped my passport last time on the way in, I don't think Canada did. Hong Kong stopped in 2013 I think. It's a shame, I like stamps. Plenty of them at Lagos last month though - 2 stamps on the way in, 2 on the way out, as well as the full page visa.
