IIRC, the KOS one never showed the seal. The one from Obama’s site always did.

The KOS site BC only shows the hidden seal found by filtering. The BC from the Obama campaign website did not.
And it was KOS who originally sent the Obama birth certificate to the Obama campaign website, and the Obama people embraced it as "genuine."
Where do you see an embossed seal on the certificate from this website you just posted?
