Brazil 2002 fruits

I have seen a few of the 2002 Brazil self-adhesive fruits in mixtures before, but never thought much about them.  They're brightly colored and cute, but the designs don't stand out well.  After seeing a few hundred of them in a hoard I acquired recently, I can now describe the three main perf types of the series.

The initial set is described as a serpentine die cut.  These are mostly under $1 each but a few go higher.  

The second series is die cut with no perfs and rounded corners, and although I see far fewer of these than the first group, they have minimal catalog value.

The third series looks like it's die cut with sharp square corners at first, but it is actually microperforated.  These are much less common and list from $6 to $20 each.

This is a tricky set to collect since the stamps are self-adhesive and often have paper stuck to the backside or sticky spots left over from a hasty attempt at soaking them.  I would collect them on paper.
 

Here are the first few types on a clipping:

And here is the full set of microperfs:
