I have a stuffed bunny that was the first gift ever given to me as a baby. It's so old and falling apart at this point, it's not really attractive any longer, and it's dingy as anything, but I love it to death. I don't even remember who it was from at this point any more, but I love it.

Other than that, it would have to be the necklace that Glacier made me that has the ashes of my foster kitty, Bear, in them. It is beautiful and I loved him very much.
