Have you seen my pen? / Did you see my pen?

1. Have you seen my pen?

2. Did you see my pen?

I was told that sentence 1 is BrE, while 2 is AmE. Is this so?

Thanks.

It depends on the context. Both are acceptable in both dialects - in the right context.

But in general, I think your belief is correct.
