There are many aspects of this business that I love. When a new set starts getting "spoiled" and you get a first look at the cards that will be coming out (as Worldwake is being spoiled right now). Getting positive feedback on eBay, or positive reviews at ResellerRatings. Helping a customer get that card they've been looking for to complete a collection. All of these are wonderful.
Sometimes, though, there are parts that are a pain in the butt.
Tonight I listed up on eBay 10 booster packs of Japanese Chronicles. The Chronicles set was a set released in 1995 (in English) to reprint some cards from the earliest 4 expansions (Arabian Nights, Antiquities, Legends and The Dark). The cards were printed with the same expansion symbols as the original set they were from, but with white borders instead to to follow WotC's policy of using white borders to distinguish reprinted cards.
In 1996 the set was released in Japanese, with the significant difference that they were printed with black borders. Now there were cards that had early set expansion symbols, but Japanese language and black borders. This has led MANY a person to believe (incorrectly) that they had in their possession, for example, Japanese Arabian Nights cards (Arabian Nights was only ever published in English).
[SIDE NOTE: This same problem happens in German, French, and Italian thanks to the reprint set Renaissance - feel free to read this post to get a more in-depth treatise on that set.]
The pain-in-the-butt part of this experience is that I can, NOWHERE, find anyone else who has these blasted things for sale. NO ONE. NADA. ZIP. As a result, I have no prices to compare to in order to determine a fair market price. A quick Twitter request yielded one person with an opinion (thanks, @mtgmetagame!), and that's all the data I have to work with. I vaguely remember someone on eBay having them for sale a while ago, at ~$16 per pack. The fact that they are no longer up would suggest that maybe they sold (if I am in fact remembering correctly). So, what to do?
I finally decided to list them for $20 per pack. Too much? As my father once said to me, "something is only worth as much as someone is willing to pay for it." So, if in a month's time or so these haven't had a single sale, I may consider dropping the price on them. For now, as the (apparently), only game in town - if someone wants a Japanese Chronicles Booster Pack - they need to come see me!
[SIDE NOTE PART DEUX: I also have available Booster Packs of Renaissance in both French and German should anyone be interested in those as well!]
