First: welcome to CCF
Based on the images, this is likely a crude counterfeit/fantasy or even a badly damaged and altered 1868 issue. I suspect if you measure your questionable coin you might find it to be both overweight and too large in diameter; that would be a good place to start. A similar coin popped up on another site about 3 months ago, which was 1.5" diameter and 26.4g vs 0.90" diameter and 6.2g for a genuine
Two Cent Piece.
Things I noted:
1. The 1863 J-316 pattern (of which 12 are known, all Proofs) was of a unique motto variety somewhere closer to the large motto than the small motto in size, but with the spacing of the small motto type. Your coin does not match - the tops and bottoms of the letters are much too close to the ribbon.
2. The surfaces are mushy, have a porous/cast/bubbly appearance, and pitting.
3. The style of the devices, and the date in particular, are extremely crude compared with the pattern. The date is way too large, too mushy, and way too close to the rim.
4. The numeral 3 in the date is completely wrong vs. the pattern issue.
5. The obverse lacks denticles entirely
6. The D in UNITED is missing its top serif -- this is correct for J-316, which was struck in the late 1860s-early 1870 using a modified 1864 L/M obverse hub and an unknown 1865 or later reverse hub. However, since the missing serif occurs on many 1865 issues and all issues dated after 1865, this is not diagnostic.
If the weight and diameter check out OK, your next stop would be to have PCGS, NGC or ANACS review the coin, verify authenticity, and put it into a plastic "slab" holder. A local coin shop or dealer would be able to advise you on how to submit your coin to one of those services.
