It's probably real, there's alot of 1797 twopences out there. 2 ounces is also the correct weight. Forgeries would be uncommon I would think. Firstly because the series never took of in circulation most due to their sheer size and secondly the're not exactly scarce.
Contemporary forgeries I would think would have been hard to make and the amount of copper required would have probably been costly.
