JUSTIN HINH'S DANSCO LIBRARY

"Dansco Dude" Justin Hinh kindly provided this overview of his new library. Thanks - looks wonderful! -Editor

I thought readers would enjoy this update on my Dansco library and preservation project. When I moved to Los Angeles last summer, I was lucky enough to convert a garage into my new coin album library. It took many months of design and renovation, but the library of 1,000+ coin albums & folders is complete.

  • I expanded my coin album preservation project to cover other album manufacturers, including Whitman, Mehrig, Library of Coins, & Warman's.
  • The coin boards in the background all came from David Lange's personal collection when I ran the Coin Board Hoard Sale in late 2024. Some of them are the finest known examples.
  • The frames on the top-right side of the room are from my visit to their manufacturing plant last summer. It shows their process from stock paper to an album.
  • Lastly, a 3D printing station to help me continue building my AI coin-sorting robot

While building out my library, I faced two interesting challenges:

  1. How can I save my collection in case of a fire?
  2. What is the ideal humidity to store coin albums?

Regarding how to save my collection from a fire, I posted this question on the PCGS forums and received great advice from a forum member with 48 years in the fire service. These were his thoughts:

Worst to first:

  1. Dry chemical. Is very corrosive and a mess to clean up.
  2. Halon and its various off shoots are very expensive to buy and refill. Displaces oxygen. No O2, no fire but can be dangerous to use in a small space.
  3. Pressurized water can will work on Class A ( wood, paper, etc. ) fires only. Can be a little messy to clean up.
  4. My recommendation is C02. Pressurized carbon dioxide. Works by lowering the temperature. Very little cleanup. Inexpensive to refill.

Justin Hinh Dansco library 5 Fire Extinguisher Based on his recommendation, I ordered this Amerex 20-lb carbon dioxide fire extinguisher for $170. It also has the added benefit of not damaging any electronics.

For the ideal humidity for my library, I saw a lot of mixed answers online. Luckily, I stumbled upon the answer when the National Archives stopped in Los Angeles during their Freedom Plane National Tour of our nation's founding documents [Constitution, Bill of Rights, etc]. The curator told me that the documents are kept at 50%. I figured, if that's good enough for the Constitution, then it's good for coin albums!
