Where might this Roman coin be found?

I bought a coin like this in London on Portabello Road in 1998 for a pound. I live in Kansas, and at the time, I was amazed to buy something from the 5th Century A.D. The guy had a bucketfull.

Are these often found in England?

It's a very small coin featuring the Emperor Honorius.

Thanks!
