It'll be fine until you let air out of it or you get a flat. Then toss it.

You'll even be able to top it up but once the air pressure inside falls to zero the left over part of the pin and the seal will fall into the tube and you'll HAVE to change it.

But for now it's OK.

If you do leave it until you get a flat then I'd suggest you only pump up the tire with the stem upwards and pointed down so the valve seal tends to stay in the valve body.
