coin denomination left to the discretion of my responder
You both took me at my word, focusing squarely on the 1959 LWC
Unless it has some sort of sentimental value it's worth exactly 1 cent.
I've done the same, I had a large collection of wheat cents that were cleaned...,
I muse that if this is done often enough in the next 60 years, a no longer common EF-40 LWC
from 1959 will gain value.
I assume you both could and would as easily substitute a '59 Jefferson into your response. Meanwhile, back at the ranch, I cannot divine a 1959 silver which lacks added value, so I'll wander here in desperation.
I'll adopt the chosen denomination but mess with it a bit, if you'll allow. What I'm attempting to accomplish is to get a bearing on the mind of some devout numismatists. Bearing in mind that nothing of the sort has been minted since 2013 or is likely to ever be minted again (too costly!) would it alter your responses if it were a 1959 Canadian penny? Or would you act with the same lack of hesitation?
Given the option of choosing between a very interesting coin or a rather valuable one, I'd choose the former every time . My vexation lies in the fact that the two so often coincide.
