You will probably want to give it an Acetone bath to remove the gunk, and take some better photos. You got a ways to go if you want to push it out as a new find.
that bottom of the "3" would make it about 2/3rds the height and about 1/2 the width of the 5. So was the 1943 Date dime stamp 2/3rds the size of 1945 ? acetone bath would help remove the contaminants (gunk - like the dark stuff) on the coin.
Please read this thread for info. And be careful. https://www.cointalk.com/threads/proper-acetone-procedure.193708/
Not allowed here. Doesn't matter, though, nobody here is likely to make an offer for yet another pareidolia specimen.
