Crusty and rusty. Personally, I like it. Great detail and a nice patina (and probably more in my price range). I should look so good at 226 years old, lol.
Two coins. The first one, a dime, has a gash in the right obverse field. The second, a gold Eagle, is raw and has hairlines.
Not a US coin which appears to put me out on a limb, but this Taylor Soho restrike pattern falls into this category. This was one of a couple missing examples in a run of 12 varieties with different reverses paired with the obverse die, or double reverses and each uniquely struck in aluminium that appeared on eBay a few years ago. Of the others, most have corroded surfaces suggesting they may have been in the same place when the damage was done. This is Peck type R24, which although not known to him in this metal, its existence was likely. As the metal was only commercially available from 1884 and Taylor died in 1885, these patterns will have been struck in a then precious metal. A combination of proof surfaces and choose your own adjective for the bits that aren't.
This one suffers from ED, environmental damage. Sadly, if it had shipwreck provenance, it would have better value, I assume.
