Thimble and Wheat

After dropping my bicycle at the shop, I decided to go try Lion's Park again, in hopes to find some more old coins.  I found a 1945 wheat penny and a smashed thimble.  I have seen other detectorists find thimbles, but this is a first for me.  I also had hope that it was silver, but it was aluminum.

I lined up the coins by decade.  Bottom row is from the 200x, and the next row up from the 1990's then 1980's, 1970, and then one dime from 1967, and the 1945 wheat penny.  I would like to be seeing more from the 60's.
