Okay, these are the "going" rates for the pins (I don't know too much about Ariel but I usually check ebay for completed sales of these pins). I will also list the original retail price (ORP)..
- $10 USD (ORP), now going for $30-50 USD
unknown, although I did see that lunarbasket has this for sale, but only the Ariel, not any portion of the magnet/dress
Pin 9487: Princess Ball Event Princess #6 - Princess Bride Ariel - $12.50 USD (ORP), now goes for $30-75 (although last sale was a best offer from $39.99 USD)
Pin 9655: DCL - January 2002 Artist Choice Dangle (Ariel) - $12.50 USD (ORP). Not sure what it has gone for in the past.
Pin 9801: Disney Auctions - Valentine's Day 2002 ( Ariel and Eric ) - $30.03 USD (ORP), pretty sure this goes for at least $100-200 USD
Pin 12707: WDW - Pin Pursuit Map - Princess Pin Event (Framed) - $214 USD (ORP), now goes for $300-500 USD
*the whole set last sold on ebay for $350 shipped in December and had a missing jewel for one of the pins but came nicely displayed in a shadow box*
Pin 13583: M & P - Ariel (Green) - 650 yen (ORP)
*right now on ebay for $65-75 BIN;
Pin 13586: M & P - Ariel with Flowers - 650 yen (ORP)
Pin 14498: Japan Disney Store - Theatre Pin Series #13 (The Little Mermaid) - 800 yen (ORP)
*last sold on ebay for $11-40 USD in January*
Pin 15223: DL - Princess Castle Series (Ariel) - $8.50 ORP).
(note there is the WDW one where she's wearing a pink dress on ebay right now for $20 USD although that one has previously sold for $3-8)
The white dress one from DLR last sold on ebay for $8.99 so this will probably be the cheapest one you can find.
Pin 17252: WDW - Ariel and Prince Eric Dancing (Framed Pin and Sketch) - $55 USD (ORP), goes for $100-200 (could go for less if you find it on auction and someone forgets to bid)
Pin 30591: Disney Auctions (P.I.N.S.) - Ariel & Prince Eric Heart - $12 USD (ORP). This pin goes for $100-300 USD
Pin 30592: Disney Auctions (P.I.N.S.) - Stitch in Raingear - $12 USD (ORP).
Pin 83748: DLR - Artist Sketch Series - Lithograph and Pin - Little Mermaid - $19.95 USD (ORP). I think this goes for $50-100 USD now.
