I recently finished going through about $60 of 5¢. I found a 1972 that was a big improvement on my existing one. If you're interested, you can have my 'old' one gratis, but I must warn you it's pretty crook. It seems to be pitted on both sides with tiny marks, as though it's been sand blasted or something similar.
At least it will fill the space until something better comes along.
