The Marin History Museum welcomes donations to the collection!

Through the generosity of individuals, families, businesses and organizations, the Marin History Museum has collected over 20,000 historical artifacts and 200,000 photographic images that tell the story of Marin County and its people.

If you have an item or collection related to Marin County history that you’d like to donate, please contact Heather Powell, Director of Collections and Administration to make an appointment.

As of September 2025, a monetary “caretaking” donation to purchase archival housing materials must accompany all approved donations to the collections. A table of fees is available upon request.

Please do not mail items to the museum without making prior arrangements.
The museum does not accept anonymous drop-offs.

Donations to the museum are tax-deductible, however, MHM does not offer appraisals.
