1905 O Barber dime. Micro O?

[Tuberale]

If I am seeing this correctly, the micro O mintmark is almost exactly the same width as the knot in the wreath, while the regular larger O extends to the bow on the left.

 

[CoinHELP!]

It doesn't look micro because the micro O is more rounded and less oval.

did you find that metal detecting its preserved very well

No your coin is not the micro O example, here is a true micro O for comparison notice the space between the knot and the top of the mintmark as well as the space between the rim and bottom of the mint mark.......
