Which type of collector keeps their collection a secret, avoiding sharing with others?

The term "closet collector" refers to individuals who maintain their collections in private, often choosing not to disclose their interests or the specific items they own to others. This type of collector prefers to enjoy their collection in solitude, which could stem from personal preference or a desire to avoid external judgment or influence. The act of keeping their collection a secret allows them to engage deeply with their hobby without the pressure of external opinions or comparisons.

In contrast, other types of collectors typically have different characteristics associated with their collection habits. For example, "cottage collectors" often share their collections within specific communities or with friends, while "isolated collectors" may indicate a degree of separation from the collector community but do not necessarily keep their collections secret. The term "enterprise case" does not describe a type of collector and is more aligned with a context in law enforcement or organized crime. Thus, the term that accurately describes someone who keeps their collection secret is "closet collector."
