It's hard to vote in the poll, due to we just have so little information to work with. Here would be my guesses.
The T206 set was issued over 100 years ago. For most of those 100+ years, probably 99% of the population viewed T206 cards as worthless pieces of paper. I would guess 99% of the T206 cards have been either thrown away or destroyed, or just haven't been found yet.
It seems 45 to 70 Wagner's (various opinions) still exist. I would think that is more than 1% of the Wagner's created. Maybe 10%. The Wagner was known as rare and somewhat valuable, but by what percentage of the population - 5% ?
So that's my guesses. Around 500 Wagner's were made, 10% are left.
One thing I am certain of. More Wagners will be found and pop up over time. That is one of the great things about our hobby. Stuff is always being found that was lost, misplaced, or just not known to be valuable.
