Australian Stamp Error?

Hi guys

Im new to stamp collecting so sorry if this is stupid

I got the same stamp but dosent it look like the right one is different? The neck is shorter in my opinion
Can anyone explain? Is it a error?

Suggestion: Please try to Identify the stamp before posting,

Nothing amiss, you have probably been mistaken by the Postmark/s, it can play tricks with your eyes.
Easily proven, just take a decent scan of each, crop the image to the design borders,
then using your mouse, toggle between the images.

These exist with flaws and varieties but design remained consistent.

It does look different, but I'm sure it isn't. I think it's because the stamp on the left is off centre, with the perfs at the bottom close to the print. The one on the right is upward shifted, so they appear not to line up.

I think it is just the way the stamps were scanned and agree with rod222.

probally right guys
im a stamp noob

The positive here is, you have a long and enjoyable journey of learning,
we all started where you are.
Enjoy the trip.

can you scan it and post ..try to send scanned stamps not to photo by camera
