I found a couple of examples using this noun; neither makes a lot of sense. i
think that ご存じ is an irregular polite form of 知る. However, if that is the case
it is a bit odd as the polite form of a verb is a noun, though that wouldn't
be the weirdest thing i have encountered with keigo. i have seen it used as
**name** をご存じですか can i used any noun is such a way? if so what is the
particle?

The other example i have is the following sentence:
ご存知だとは思いますが、クオーターしかつかえませんよ。 which i have a couple questions about; first what
the hell does ご存知だ say? i dont understand the だ at the end of this noun is it
a particle or marking past tense of the knowledge? The クオーターしかつかえませんよ is
confusing cause it isn't written in kanji but i believe it is
クオーターしか使えませんよ。but even that i think should say クオーターしか使えますよ。 as the katakana
is quarters しか is nothing but or only and 使える is serviceable or useable/ can
be used.

lastly i find the は a bit weird here, why can it go after the と i have never
seen that before. (と **は** 思いますが) i am assuming it being used to makr the
direct object like one can use では or には, etc.

question

ご存じ how to use properly and why
ご存じ is not a verb in the first place. It's a honorific **no-adjective** that
has to be used with だ/です. You can think it roughly corresponds to
"familiar/aware" with respectful feelings. I don't know why, but there is no
direct honorific version of 知っている. Whenever you want to say "someone knows
something" with respect, you have to use this no-adjective and say 彼はご存じです and
so on. (You may think お知りになっています should work, but we don't usually use this
for whatever reason.)

By the way, a humble version of 知る/思う is 存じる, which is an ordinary verb.

This は after と is a contrast marker. It's optional here, and you can drop it
without largely changing the meaning.

クオーターしか使えますよ is ungrammatical. しか is a [negative polarity
item](https://japanese.stackexchange.com/a/16060/5010) and must be used with a
negative expression. This is a basic rule which has nothing to do with ご存じ, so
please recheck your textbook.

> ご存知だとは思いますが、クオーターしか使え【つかえ】ませんよ。  
>  I think you know this, but you can use only _quarters_.
