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.
To me, it's machine/mechanical doubling. All of the "shadows" are evident in the same rotational direction. It is a die loose in the holder and the doubling will stop when the holder is tightened.
1878 8 Tail Feathers (8TF) VAM-18 (Doubled Date): Features clear doubling on the date, letters in "LIBERTY," and the motto. 1878 8TF VAM-5 (Doubled RIB): Known for distinct doubling at the base of the letters "RIB" in "PLURIBUS" on the reverse. Because 1878 dies were frequently experimental, there are dozens of minor doubled dies. Prices range wildly depending on the specific VAM, the coin's condition, and whether it has a Prooflike (PL) or Deep Mirror Prooflike (DMPL) finish. Common varieties in circulated condition may carry modest premiums, while top-tier varieties in high Mint State (MS) grades can fetch thousands. To verify if your coin is a doubled die, check the date, "LIBERTY", and "E PLURIBUS UNUM" with a 10x jeweler's loupe for signs of notched letters, rounded edges, or split serifs. The "notched letters" and "split serifs" are keys to true doubled dies. I don't think yours has those features, but wait for an expert opinion.
That coin has definitely seen a harsher cleaning. I’m not seeing any signs of doubling other than machine doubling. It’s also the 7 tail feathers variety. Shame about the cleaning as that really lowers the value. The values are higher as only 749,500 were minted of this variety.
