UV Protection and Mounting Tips for Memorabilia

Displaying sports memorabilia has gotten complicated with all the UV concerns and framing options flying around. As someone who’s made mounting mistakes and learned from them, I learned everything there is to know about protecting displayed items while showing them off. Today, I will share it all with you.

The UV Problem

That’s what makes display decisions endearing to us collectors who care about preservation — we want to enjoy our cards visually without destroying them. Sunlight is the enemy.

UV damage causes:

  • Fading of colors and ink
  • Yellowing of paper stock
  • Brittleness over time
  • Surface degradation

Damage is permanent and cumulative. Even “indirect” light contains UV rays.

UV-Protective Options

Probably should have led with this section, honestly. Modern framing materials block harmful light while allowing display:

  • Museum glass – 99% UV filtering, minimal reflection, expensive
  • Conservation glass – 97% UV filtering, more affordable
  • UV-filtering acrylic – Lighter weight, similar protection
  • UV-blocking film – Can be applied to existing glass

Mounting Without Damage

Never permanently attach valuable items. Reversibility is everything in preservation.

Safe mounting methods:

  • Photo corners – Hold items without adhesive contact
  • Archival mounting strips – Reversible adhesive
  • Slabs in stands – Let the case do the work
  • Hinges with Japanese tissue – Museum standard for paper items

Avoid: tape (any kind), rubber cement, spray adhesives, pressure-sensitive mounts.

Environmental Factors

Beyond UV, control the environment:

  • Temperature – Stable and moderate (65-70°F ideal)
  • Humidity – 30-40% prevents warping and mold
  • Air quality – Away from smoke, cooking fumes, and dust sources

Shadow Box Displays

For jerseys and larger memorabilia, shadow boxes with UV glass provide protection while creating dimensional displays. Use acid-free backing materials and ensure items aren’t pressed directly against glass.

Rotation Strategy

Some collectors rotate displayed items quarterly. This spreads light exposure across the collection rather than concentrating it on favorites. The items in storage rest while others take a turn on display.

Your most valuable items might be best kept in dark storage with photos on display instead.
