Some information on Bend-Ems figures....

Series 1-13 would probably fetch around $50 - $75 if you are lucky.
Series 14 would fetch about $15 - $20.
Series 15 can fetch as much as $500. I know of many people willing to pay $100+ for everyone in the set except for The Rock. I sold my MOC Scotty 2 Hotty for $200 on eBay.
The ones that come with gear will fetch a little more than the regular ones.

Series 15 is really the only set that's worth money but trust me -- it's VERY hard to find one figure from the set...nevermind a complete one. It took me nearly 3 years of constant searching on eBay to locate just 2 of the 5.

Some other stuff that was released by Justoys Bend-ems:

Powerhouse Boxset: Re-Releases of Previous Sets
4-Pack Boxset: Re-Releases of Series 1 Minus Luger
Bend-em Ring (each came with different inserts) 2 Bend-ems Figures, Paul Bearer Exclusive and some as is
Many Bend-em figures came on an all black card with no picture (I.E. Lex Luger)
Canadian Package Varations for Series 4, 5 and 6
2-Packs: Not sure if I can re-call the name correctly but I think it was called Famous Fights. Series included 2-Packs such as Mankind/Undertaker & Faarooq/Ahmed Johnson

Unreleased items include: Mini Dink, Adam Bomb, Larger different WWF ring and every paint job from Series 2 changed from the production stage to the actual release stage.

Series 15: Scotty 2 Hotty, The Rock, Grandmaster Sexay, Rikishi, Tazz

i remember someone on this board getting two series 15 figures for $3 each on ebay about a year ago!

Thanks for your information chaps, been great!

If you are referring to the bottoms of their boots -- no there is no difference in value.

Well, I would have done the exact same thing. I mean you can't go wrong with spending $3 on something that is worth so much more.
