No, there is no special difference, the hands are chosen to minimize (not)
seeing them being an octagonal shape perceived to be circular etc.
If one has the grounds for claiming that
1. there are propositions
2. some are true propositions
3 there is no need to say anything about why they are true
Then
I know that 23-6 - 15 is true is enough to claim that one knows there is at
least one true proposition, by the quantifier (in 1) one knows there is an
external world, since the knower is not such a proposition

I am not sure why "Here is a hand" is supposed to be essentially different
from any other empirical proposition. It just happens to be one that is easily
verifiable; I cannot easily verify the location of Salzburg from where I am
sitting but I can always stare at my hand, touch it etc. So the issue is
whether (verified) empirical propositions can supply knowledge.
For the record, I was thinking of this philosopher I like:
He writes for the Aristotelian Society:
"It is surely clear that if I were now to say
i. Nothing is the case which would make it false for me to say that the palm
of this hand looks pink to me, though I do not rnean to imply that I or anyone
else is or might be inclined to deny that, or doubt whether, it is pink.
this would be a perfectly inteliigible remark even though it might be
thought both wordy and boring. Indeed I am prepared actually to say it."
"Consequently, although you may be right in claiming that it has not been
shown that the implication of the futfrlment of the Doubt-or-Denial condition
is detachable (and indeed it may well be non-detachable), you must be wrong
in thinking that this implication is not cancellable."
He further uses the example "I have a pink sense datum", a few minutes before
he provided the full
ii. The palm of this hand looks pink to me.
-- repr. in Warnock, "The philosophy of perception".
A study of G. E. Moore's proof of the external word and his handy manoeuvre
belongs elsewhere, although it may connect.
"Only connect," says Forster, since he found that for any x and y, there is
always a connection.
Cheers,
Speranza
