Possible pre-Colonial era coins???

[Snapolson]

Hi Folks,

It's probably a long shot but I figure I'll just throw it out here for you to check out.

I found three coins (about the size of a quarter) a while back in a known Colonial era spot. The Draped Bust penny is with them for size comparison.

Any ideas? I'm leaning towards British coinage pre-1800. Can anyone pin down the variety?? Thanks.
