What year is it? You can always check online against known varieties (Wexler's) and see if the doubling matches yours. https://doubleddie.com/ If there is nothing listed for that year, mint, obv/rev it is unlikely you have a discovery coin after 100+ years.
It looks flat and shelflike. So to me it's probably worthless doubling. But maybe @Rick Stachowski can chime in. He's much better at varieties.
Full pics of the obverse and reverse are needed. Morgans are mostly identified by VAM's. Welcome Pleasant William.
