Hello:
I'm new to the world of collecting counterstapmed coins and I recently acquired the pictured 1802 large cent with an eagle, olive Branch, and an oval with "US" inside. In short, I'm stumped.
I've searched Rich Harzog's extensive online resource: Complete List of Merchant Countermarked, Counterstamped Coins: A-C (richhartzog.com), which appears to be a transcription of Gregory G. Brunk's publication of merchant counterstamps, but doesn't include government stamps, which I believe this to be. Any thoughts on this? The style looks to be civil war era, but have a hunch this combination of symbols may well pre-date the civil war.
Also, I'd be curious to get some opinions about the coin's obverse surfaces (outside of the counterstamp): damaged? I ask because are some areas of roughness on the obverse, but there's no porosity/unevenness/color change apparent, so I'm inclined to attribute the roughness to the planchet quality (vs. environmental damage) . Any and all feedback / opinions would be greatly appreciated.
Thank you kindly
