Tania,
I have several of the White Horse minis in my collection,
and usually find them in good condition for $5-$10 USD.
I think yours, being in the replica case, should be worth
about $150-$200 as a set to a collector... I know that
I would be interested in them, and the other box set you
have.
I have seen a number of the White Horse statues in ceramic
selling in the $15-$25 range lately...but don't see any empty
bottles being bought at any price.
Drop me an email directly, and we'll talk more about these!
Cheers
