I have playfields in storage that are over 60+ years old, and still look relatively new.
I have personal games in my collection that are well over 30 years old (and in some cases owned nearly 30 years), my oldest game is 47 years of age.
Once wood is properly treated with lacquer such as tuff coats used in wood rails, EMs, and early SS, composite coatings for solid state and alphanumeric, or clear coats like games from 1989 and up, and the playfields / games are well treated in climate controlled environments, and the playfields waxed, they will still be around in 100 years or beyond.
Backglasses fair FAR FAR WORSE if not protected.
If a collector knows what can happen, they can even avoid some effects like "planking" caused by temperature variations, moisture conditions, and avoid use of the damn operator "cheater bar" that causes torsion and twisting on the playfield.
We are not talking about wood exposed to outdoor elements, or items that get moved constantly with glue delamination.
Nor are we talking about routed games that get beat to living hell due to operator neglect.
If someone is telling another that playfields are going to turn into sawdust in x number of years, they need to cut back on the weed.
Bottom line?
Good news, the games will outlive you, just like finely made guitars or violins.
Example:
Here is a detailed photo of a 1950 GTB Knock Out that is 66 years old in a private collection that I uploaded to PinSide a while back.
How does it look?
This should give you a happy face.
(BTW this is a REALLY nice example of this game)
