Don't clean the coin. What is the coin made of?

Don't clean it, as said. the reason is that any old coin is valued for its patina, the gradual darkening of the metal, that occurs with time. Clean that off and you ruin both its appearance and its value to any collector (or museum).
Interesting that this object has no monarch's head on it. If you are in or near London, try visiting Baldwin's (www.baldwin.co.uk for details),off The Adelphi, The Strand, or ring them They are certain to know, even from a description over the phone.

I used to collect coins when young dont know much about it now but I can tell you whatever you do dont clean it yourself I seem to remember this is a sin to the initiated.
I have a 1797 cartwheel penny what you are describing isnt that so you can rule that one out. Search google images; 1798 coin there are a few there might fit...
