I hate 1800. All the reverse dies were made from a full hub and only differ in small hand finishing details. Unless the die fails they are extremely difficult to tell apart even in nice condition. The obverse are a little easier. In the case of this one the highest wave of the hair appears to be to the left of the upright of the R or possibly below the left edge of the upright. That only occurs on two obv dies, all the other have it further to the right. So the obv is that of S-192/193 or S-210. S-192 and 193 each have a long fraction bar, S-210 has a short one. The OP coin has a long bar. So much for 210. On 192 the fraction bar slopes down to the right ending close to the final 0. On 193 it is level and ends further from the final 0. On the op coin it slopes down to the right and ends close to the 0. That would make is S-192 and it is apparently an early die state because S-192 most always comes with an arcing crack from the 1, through the fraction bar, through the right ribbon, passing just below the end of the stem, through CI, to the rim. S-193 also usually come with a distinctive arc crack curving the other way through UNITED. But both 192 and 193 are both known uncracked as well.
the reverse of this coin has a spike from the rim to the top of the I in america. i have seen this on some other 1800 large cents but at the moment i can't remember what varieties they are. there also does seem to be a die break on the reverse from around the letter U in united through around the 100 near the fraction bar. but it is difficult to see because the coin is corroded to some degree.
