It's an odd label that. The font, which looks like Bodoni Ultra or something similar, is totally at odds with liberty's current branding, so I find it hard to imagine it's completely current. It's also not a very 21st century font choice, nor the heritage Arts & Crafts / Art Nouveau-esque font they use now.
I can't find any other example of that font used by them. It's not a million miles from the label font used in the 6os/70s, but much much heavier, and I don't think it's that early. So assuming it's genuine, perhaps a short lived label style from the late 20th century.
I'm talking purely about the label, I'm not sure when the coat is from.
