It is unclear whether she was just born or not before the event in HM. More importantly, with all these hundreds or thousands years old beings, you gotta wonder where they get all the beans.
So we don't append the traditional 100 years to the age of a Tsukumogami (or do Menreiki not count as that)?
If we apply traditional 100 years, then yes, 100 beans, if we apply her 'birth' to Miko's making of her, then she would be a little younger than Miko. But it's not entirely clear when she started gaining a physical form.
It's 100 years before an abandoned objects becomes a menreiki.
So assuming Kokoro's masks were abandoned shortly after Miko's "death," (since she was the one who comissioned them,) Kokoro would be around 1,300 years old, I think.
However, we don't really know when her masks were abandoned.

Her masks were the basis for Noh play masks, so it's quite possible her 66 masks were used for generations before being retired.
