Below are different conditions for describing the significance of the thing. Significance is employed to help determine the impact the conservation service could have on the preservation and understanding of the Canadian collection and the benefit it would have to your client.

Key significance criteria
Historical - "An object or collection may be historically significant because of its association with people, events, places and themes."
Aesthetic or creative - "An object may be aesthetically significant because of its craftsmanship, style, technical excellence, beauty, demonstration of skill and quality of design and execution." An subject may also be artistically significant since it was produced by an important musician or maker.
Scientific or research - "An object or collection may have research significance if it has major prospect of further methodical examination or research… This criterion tends to apply chiefly to biological, geological and archaeological materials, but can also connect with documentary collections."
Social or religious - "Objects have communal significance if they are used in community esteem. This may be demonstrated by social, spiritual or ethnical expressions offering proof a community's strong love for an object or collection, and of how it plays a part in that community's individuality and public cohesion."

Comparative significance criteria
Provenance - "Provenance means the chain of ownership and context of use of an subject. Provenance is central to creating historic and clinical significance."
Representativeness - "An object may be significant since it represents a specific group of object, or activity, life-style, or historical theme."
Rarity - "An subject may be significant as a rare, unusual, or particularly fine exemplory case of it has the type."
Condition, intactness, and integrity - "An object may be significant because it is unusually complete, or in audio, original condition."
Interpretive potential - "Objects and collections may be significant because of their capacity to interpret and demonstrate areas of experience, historical themes, people and activities… Somewhat, interpretive potential represents the worthiness or utility the thing has for a museum as a focus for interpretive or educational programs."

So the objects we receive as gifts can play a critical role in our lives. But not all objects in our possession are special: Many of us own a lot of stuff not at all worth saving in a fire.

The special objects were those centered on life events or people — wedding rings, portraits, inherited candlesticks, and so on. Around 40 percent of the most meaningful objects in a home were either gifts or inherited.
