Hi
I am not familiar much with either of those pins terms of tradability.
If you go by purely a financial standard of the current market based on Ebay (unfortunately the only one we have readily at our disposal) the WET PAINT is selling for around $190 on average, and the Chip n Dale around $100 on average.
If you go by the Pinpics wants/trading factor, they are not too far off of each other with Wet Paint at 17/449 and Chip n Dale 21/362.
Then of course the Edition size......1000 vs 750.
without the Ebay factor I think it was a good trade, and being that you REALLY wanted the Chip n Dale that makes it more desirable.
I wouldn't have the made the trade. I would have wanted something more along the C n D for the Wet Paint. Or I would have sold the Wet Paint on Ebay , bought the C n D and then used the extra $100 or so, for other pins I wanted.
I don't mean to come across as sounding harsh or critical. I just got the impression from your second post on this thread that you wanted my REAL thoughts on the matter.
It is usually not my way to comment on a trade already completed, because regardless of the Ebay and Pinpics factor, it truely does matter that you were happy with the trade. The real valuable of a pin is in the eye of the beholder.
