from what I have heard, just let the baggage
screeners know that you have collectible lapel
pins in your bag going there... Orlando airport
is SO used to seeing them they practically don't
even look... but it probably wouldn't hurt to mention
it anyway.
at worst, they might make you open your pin
bag and examine each and every page...
Nobody I have heard of has had any problems...
last time I flew, they were more interested in
the large glob of coins I had left over from the
casino than anything else I had with me.
but I have heard, definitely carry them with you...
don't check them... you don't want to risk losing
them!
have a great time!
