Please, can anyone tell me if my sentence is usable and sounds ok?

Thak you, Om.

And can i say this: 'A coin that was on the floor almost escaped my eyes.', Does this sound ok and mean the same as 'I almost not noticed a coin that was on the floor'?

Thank you.

Yes. When referring to yourself,
do not fail to CAPITALIZE the I.


That 's bad grammar.
Try: I almost failed to notice a coin that was on the floor.
or
I almost failed to see a coin on the floor.

Many Thanks.

You can say either and both are fully grammatical, Imsak. If you are the beginner you say you are don't worry about nuance at this time. Focus on the fundamentals.

Do not trust anything Om says regarding grammar for he knows nothing at all about grammar.

Yea JTT I too am continually amazed at the dedication and tenacity of the typical esl, far beyond application of the typical American for instance

You can omit "that was" and possibly even "my eyes" depending on the context

I would've writ "I almost didn't notice a (or that) coin on the floor"
