Rare Rear View or just junk?

[BuickGS65]

Found it on a 1965 Special....Paid $3. Day/Night rear view mirror
Says "GUIDE GLARE-PROOF MADE IN USA" on top... Never seen it on a 65 Buick... Mirror has some crackling. Rare?, Valuable?, Original?, or just junk?

Looks more like a 61-63 miirror as it has the "day/night" flip control. Most 64 on up mirror had a black twist know to move the mirror.
Not a bad find for 3 bucks. Don't know how valuable though. :Do No:
Regards,

Love the Tiporillo box. Dad used to have lots of 'em in the garage full of cool junk.
