Where can I find details of the Holy and Blessed properties?

I think this usually means sanctified, though if it is blessed by a tech priest possibly immune to jam. What weapons are you asking about specificly? Sometimes it expands on this for each individual weapon.

Holy just prevents Daemonic creatures from applying double Toughness Bonus to damage?

Hmm I seem to think the IH has a catch all Sanctified/Holy quality than can be applied to any primitive melee weapon (including Lathe and mono-variants). It ignores the Daemonic trait, as well as doing extra damage to certain Unholy creatures (See Damned Cities for example).

Holy is described in Core book, but what is point of Sanctified if it just means the weapon is Holy?

The weapon is just sanctified, the damage it deals is holy damage.
If I remember correctly blessed makes a weapon do holy damage for a short time only.

Holy weapons would be relics that do much more than just do holy damage.

The only info on Holy weapons I could find was in Daemonic trait in Core Rulebook.

There is only a reference to holy attacks, not holy weapons. Attacks with sanctified and blessed weapons as well as some relics are treated as holy.
But nevertheless it is what you are looking for.

Where to find the complete rules was written in an earlier posting by Lynata:

* Sanctified Weapons are in Blood of Martyrs
* Blessed Weapons are in Blood of Martyrs
* Sanctified Ammunition is in Blood of Martyrs
* Blessed Ammunition is in the Inquisitor's Handbook
* Holy Weapons seem to be spread out across all books and are individual relics with individual effects rather than a generic type or quality that would apply to all - needless to say, Blood of Martyrs has a number of them

In addition the sanctified quality is also mentioned in ascension

The only objection I had is that there is something called "Sanctified Weapon" in IH, not just Sanctified Ammunition as in the list above. It only cost 500 thrones but is Very Rare. and can only be obtained through the Holy Ordos. It simply counts the damage as Holy. I'm not sure how this corresponds with Sanctified and Blessed weapons in BoM, there seem to be a difference there in the wording.

Right. It's a bit of a mess, both because these upgrades are spread out across various books (some only once, but others multiple times and contradicting themselves) but also because some of them do not sound very fitting in effect and/or cost-benefit ratio.

I feel tempted to write some houserule suggestions for this - currently my personal opinion revolves around making "Blessed" a temporary effect (doable by mid/high level player clerics), "Sanctified" a permanent upgrade (requires ceremony conducted by a Pontifex or Canoness), and "Holy" simply being a sanctified weapon that has been in use for centuries or millennia and thus having gained a big reputation.

I like that. The most complicated part would be working out HOW the cleric blesses a weapon. Also, IF they can (for the less-than-pure-faithy among the clergy).
