Hello all. I’m looking to sell some of my collection to help support my family. However, what I am starting with has me puzzled as to how much to ask. I have a circa 2000 Unifive repro of the Kamen Rider Bat Kaijin: (not my photo) Typically eBay sold listings are the obvious barometer, but there is only one listing that went for 168, and it was a year ago. Yahoo Japan and Buyee have no hits at all. I know asking for value is rightly frowned upon, but I’ve done my research and come up empty. Does anyone have a resource I’m not thinking of, or context for how much a Unifive repro like this could be fairly posted at?
Mandarake listings can help. If something isn't in stock and is sold out, it won't tell you when it was sold, but it will tell you how much it was sold for. I did a search for "unifive kamen rider" there and found your figure, sold for 6,000 yen at some point: https://www.mandarake.co.jp/ariaru/shop/en/item/1219829311
Completely agree with what Roger said. Not sure why you are having such problems finding any sales records, but maybe try searching in Japanese. The key terms you would want to use are ユニファイブ (Unifive) and Bat Man (蝙蝠男). That should bring up more of a history for you. I would sale that sale price is about right, likely somewhere in the 6-8k yen mark. For additional reference you can see some which have sold on Mercari even: https://jp.mercari.com/search?keyword=蝙蝠男 ユニファイブ PS - it's a great toy; I am sure there on some folks on here who would be happy to adopt it PPS - generally I would not rely on ebay pricing for this sort of thing PPPS - you totally overblew the problem here with that title, haha, this is not what I was expecting at all. Short answer is always though, stuff is worth it's value to you. And we always have different metrics when it comes to that. Good luck!
Another thing I will just add is that, while there are no dates visible on the sales, so you don't really know (as Roger said) when these sold, this also gives you some idea, by looking at sales from other shops, that the above is not a random 1-off:
If you have a large collection of Japanese toys and could use a good bit of data I think the best resource is an Aucfan premium membership (https://aucfan.com/). For just under $7 a month you can sift through all Y!JA sales records over the last 10 years. Probably overkill for most users but definitely a valuable tool for some.
I’ve seen aucfan come up in image searches for random Japanese toys, but I didn’t know what the site was! That’s good to know!
