I am a not-too-serious collector of UK copper and bronze, but I had a 1904 "bright finish" farthing variety on my list, and grabbed what appears to be one in a junk 50 cent box of world coins at my local shop.
In hand, this looks very similar to post-darkening farthings. I can also tell you that I have found a few nicer-grade examples of Edward VII and George V bronze coins in that same location. My local dealers mostly disregard these coins as they are after gold and silver.

Are these scarce? Are they frequently faked somehow? Does mine look like the real deal? Any advice would be much appreciated!
