The same goes for lots of muppet stuff, even though something might be quite rare and hard to find, it depends how much someone wants it to how much its worth.
I bought a fisher price kermit a while ago on a market for about $5AUD and its not in that great condition so would only be worth about that anyway. I took it home and washed it and touched up a few of the scratches on his eye with permanent marker making sure not to get any on the part of the eyes thats supposed to be white.
All the dirt was gone from the kermit and it came out really nice and looks quite new now but still not worth much, he is worth lots to me though because you dont often see kermit toys here let alone old ones.
