If it's genuine, yes, I'd call it a decent deal. It's the most common Trade Dollar, but that's a relative term with Trade Dollars, and they don't exactly grow on trees with as much detail as yours shows. Even worse, the polishing was so hard that it likely removed details itself, so the technical grade of the original coin might even have been higher.
Either way, that coin has changed hands from someone (some past owner, not necessarily the one who sold it to you) who had so little knowledge and respect that they wrecked a valuable coin in the interest of making it "pretty," into the hands of someone who can appreciate and respect it. This is a win.
The best thing about a bicycle is that it uses no gasoline, therefore the chance of fiery death is greatly reduced.
