That’s (substantially) more than I have as #5 at a startup. Truth be told I didn’t pay attention to this when joining because at the time they hadn’t yet set up their EMIs and I was told that negotiating for share options is pointless since their expected value is close to zero. So, if I had insisted I could probably have gotten more. But it’s neither unheard-of, nor even particularly rare from what I’ve heard (in the UK).
