When buying Leica cameras collectors often pay more for “brassed” models. That’s where the paint has worn away with use to show the brass metal underneath. I guess it’s supposed to show that the tool was used for a long time in the field.
With these intel chips it’s a similar story. You’re looking for authenticity.
Not really. In this case, collectors are looking for scarcity (or rarity, whatever the right word is here). These chips are no less authentic than the mil-spec approved chips they sold at the same time.
Personally I like used lenses and cameras more, especially with strong signs of use at specific locations.
It somethings also indicate that the lens got lucky in production and is sharper or without flaws.
