Although it's pretty cool that 1959 cents are the first year with Memorial reverse, I don't consider them to be more special than the other copper dates. Although not common, they are not rare either. I find them occasionally and not less often than some early 1960 cents.
I find it surprising on just how many I still find in circulation.... I will either spend them or throw in the copper pile unless they have good detail and good luster.
Back about 20 years ago I was playing poker and the woman who was hosting the game said she had a coin with an error, she said it had V's where U's should be. I told her it wasn't an error and that's the way they did it back then, but then she told me she has some more coins. She knew NOTHING about coins, so I really don't think she was making this up, but she was naming the coins she had, there weren't many, and she said a 1959 wheat penny. I told her she didn't have one because they didn't make wheat pennies in 1959. She said she had one. She told me she would have to dig it out to prove it, but we were playing poker, then we both forgot about it. At the time I didn't know there were "mules" like that or I would have been begging her to go find it and show it to me. I just figured she was mistaken. To this day I don't know if she had one or not, but I do know she wasn't pulling my leg because she knew nothing about coins at all, meaning she wouldn't have known to make up something like that.
