The mint mark is usually very prominent. Even on old well circulated coins the MM is legible. Your small date is 100% Philly.
For anyone who's interested, I Googled "Becks Variety Lincoln cent" and this popped up. I don't click on You Tube videos so I don't know what the OP's coin is: https://www.google.com/search?q=bec.....69i57j33.11211j0j7&sourceid=chrome&ie=UTF-8 One of the videos is on a "Hidden D" 1982 copper cent (small date). There's also an old Coin World article on Beck: https://www.coinworld.com/news/precious-metals/new-doubled-ear-discovery.html
@Alexander Sanchez Baba Beck? YouTube nonsense! Stay away from his videos! Mirza Beck (Baba Beck) was an old member who no longer posts here on CoinTalk. Here is an old thread with his garbage https://www.cointalk.com/threads/becks-1972-4-1974-1983-ddo.320215/#post-3138024
