Also there are rubber stamp with this slogan which stamp collector call commemorative special cancellation or slogan cancellation.
Not sure whether this is officially issued by P&T department of India or personally made by some collectors like we see this all the time.
My personal opinion (Expert Certificate) for this is that is an ART work rubber stamp made by some collector/dealer.
It's very easy to make money by selling this kind of slogan cancellation or special cancellation.
Truth is God slogan cancellation was selling for $16 and $8.
Don't you think this is possible by just investing in RUBBER stamps and start selling it or send it to collector friend who will glorify this rubber stamp as genuine.
So what are chances of this as FORGERY even if it was officially issued.?
Following are mostly all BOGUS (never exist) or Forgery which will help you to decide about slogan cancellation of Gandhi "Truth is God"
1) India 1911 Allahabad First Aerial Mail Post Commemorative cancel or Special cancellation
