You can use MOC, MIB, MIP (Mint In Package) to describe toys that are either sealed or loose that are in mint condition, although people tend to assume that they're loose. Toys that are sealed mint are described as:
MOSC = Mint On Sealed Card
MISB = Mint In Sealed Box (or Bag)
MISP = Mint In Sealed Package

Another term that some people can familiarise themselves with is NM = Near Mint and also LM = Loose Mint - and thus you can have acronyms like NMIB or LMIB (Near Mint In Box and Loose Mint In Box respectively). These acronyms are commonly used by collectors and in toy publications like magazines, price guides etc.
