Yellow Bubbles

[Leemcl]

I've noticed that the bubbles I have that have had minor issues, like small hairline cracks or worse never seem to yellow.

Tri Logo also, generally don't seem to yellow...

Is there a reason for the above or is it just pot luck ?

Must be to do with the plastics used. Tri Logos never seem to yellow, whereas, POTF are the opposite. ROTJ bubbles often yellow and some ESB do as well. Don't think I've seen a yellow SW card. Some of the Mexican cards have a tiny whole punched in the back of the card, which probably helps due to the airflow.

Sadly there are indeed some yellow SW bubbles as well. Most seem to still be clear, but I've seen several Palitoy 12 backs with yellowed bubbles, including some graded as yellow for what little that's worth!

You'll find that one in the FS section on here as well

The plastics used for the bubbles changed after a certain point and some simply never suffered from the yellowing.

I have a couple of trilogos with yellow bubbles, so they aren't 100% immune either
