What I have been doing is what you suggested, using separate snippets for each entry.
Important items can be created as their own "Named Item" entry, so you can put all the details there and let RealmWorks auto-link to it. Then you can reveal details as necessary.
For more mundane items, I am not bothering to enter a value. I expect that most of them will be available as entries in a rules set, eventually. I use HeroLab to track the party's possessions, so I let HeroLab take care of the details of who got which items and what the value is.
When it comes to appraisal, you can add the appraised value to the snippet for each item, if applicable. Cash, of course, would not have such a thing usually. Likewise, notes about things skimmed from the hoard before anyone else notices can be added to the unrevealed snippet.
At the moment, revealing snippets is for the whole party. One of the more common requests I have noted has been for "per character" or at least "per player" reveal/ conceal state, and that seems to be on the drawing board. When that is implemented, the skimming will be easier - just reveal that item to the one who took it. However, that will also make it necessary to be a little more clever with breaking out the value from that entry until known.
It may be that a specific type of snippet with "partial reveal" state, or a complex entry made up of multiple snippets grouped in some way, is desirable.
Identification is more complex, as that may apply more to some genres than others. A pair of snippets for each such item, one the "unidentified description" and the other the "full description", might be appropriate. That level of information management seems appropriate to a full "Named Item" entry... +1 swords (as a d20 example) are common enough that you would not want to create a "Named Item" entry for each, and they should not share a generic entry; so that leaves the notion of a pair of snippets. In that case, details can be copied from the unrevealed "full" description to the revealed "player" description as needed.
I think sometimes we get so caught up in the ability to reveal every snippet that we forget we can plan on creating some we have no intention of ever sharing.
