All of the times I used to get these, I have never seen them flipped around like that, though I am sure it COULD be an error from the manufacturer, I have no way of actually knowing.. Be very careful with those, the "30" on the bottom one, looks a little smudged to me, and I have had fake M 30s before, and this is what happened, the 30 and scoremark were actually perfectly lined up with the M on the other side.. but, they(the fakes) would be a bit "lighter" or more of a pure white colored, than the real ones, which are/were usually light blue, with little blue specks in them if you look closely, IME.. and I don't recall ever once seeing a real one with the score mark flipped like that, that bottom one in the picture, looks like the imprint is slightly "off" or kind of not lined up totally perfect, which was another sign when I would get ripped of with fake M 30s (made from chalk or some other chalk like shit), the score marks and imprints would sometimes be crooked, smudged, or just off balance, with the "3" slightly higher on the pill above the score mark than the "0", where the 30 is.. or vise versa, or the "M" inside the box would be a little different, or smaller than the regular one on the real pills, but you would have to look at it next to a real one to really notice.. when I did, get ripped off, it was usually because my connect got ripped off, and didn't even know she fake ones.. I would be so sick and so pissed usually when this happened, and would taste the difference immediately when sniffing one, and know that shit wasn't real, because it didn't have that bitter oxy taste, it was more of a pill with no taste, kind of taste lol(if that makes any sense). But I would always tell her, she was a white lady, who would sometimes go to the hood, where people would sometimes rip her off, because she was sort of bitchy.. but she was cool as hell to me, always! and always refunded my money or gave me real pills to make up for it, usually throwing in an extra one or 2 to make up for the bs.. she normally had her own script, but would run out early from so many people, like me, who would constantly be calling her for more.. now, pills aren't a thing down here AS MUCH, in FL where I am from, at least not as much of a thing as they were 5-6 years ago, with all the fake pain clinics, and cheap oxy prices.. back then you didn't have to worry about fake oxys, because they were so fucking cheap, no one even bothered making/selling them, until the price of them on the street nearly tripled here, then the fake A215s and M30s, started showing up randomly.. all my connects were very cool to me though, and they most always re-imbursed me when this happened.. A good way to tell if these are fake is to lick you finger and touch one of the pills, the faker looking one of the 2, and see if it has that bitter oxy taste.. not sure if you know the taste or how you do them, but that's a good indicator usually, but be careful as the newer fakes aren't chalk based with nothing active in them usually, they now are made with fentanyl or one of its cousin RC analogues, which is very strong and dangerous to take in unmeasured, microgram doses.. and even then, isn't very safe!
