Curse: Loose an object with higher value

[BeniJmnz]

In Spanish, i have a curse that says: you lose an object with higher value

I have look for this card here:
http://www.worldofmunchkin.com/game/cards.html
but i don't find any curse similar to this

I have a question. If i don't have any item with bonus, do i need to discard any item to complete the curse?
For example, i have this card on table:
- Loaded Die
- Wishing ring
- Boots of Running Really Fast
- Tuba Of Charm
Do I need to discard any of these items with this curse?

Another question: Really Impressive Title is an special card without gold value. If i receive that curse (or another similar one to remove an item), i have to discard this one?
