Does look like one, to be sure would be better without the lines, although you have it in hand and should be easy to tell.
A good indicator indicator is a gap between the last 1 and the tooth below.
Also your own seems to hang over the right of the tooth rather than above it.
These are only tiny differences and why its often confused with the common one.
I am more drawn to being the common one Serifs and gap dont look right although would be much better without the last line which is a distraction.
