Lowest Card Price is Now Picked Using Ebay Listings

With the release of the Yugioh Prices Android app, it’s now time to begin a new round of development on the website!  To get the ball rolling, we are changing up the rules we use for determining what the lowest price for a card is.

Up until now we’ve just been going off of whatever the lowest priced listing our API could find was, but after talking with some of our users we’ve decided to tweak this so that the lowest price for a card is now determined by the lowest priced eBay listing.

There are a couple reasons behind this decision, the first of them being that the lowest price shown for a card is intended to represent the most accurate assessment of what that card is being bought and traded for person to person, not vendor to person. The second reason for this change is that due to the technical limitations of the APIs we have to use to get listing data from certain vendor websites, we are unable to automatically factor in shipping costs for cards, which in turn can sometimes throw off the lowest price for a card because a vendor will pad out their margins on a sale through their shipping costs.

We aren’t sure yet if we’ll be keeping this policy forever, but for now we’re going to try it out and see how our users like it.

Anonymous asked: I sell a lot of yugioh threw your app on my iPhones but for some reason I'm having a problem linking this app to my ebay so I can sell my cards threw the ipad. Any help please?

Ebay’s authentication token system can be pretty finicky at times, especially on a mobile device.  If you can’t seem to get your app to authorize with eBay, the best solution is to simply reinstall the app.  This (should) clear away any lingering cached tokens that are mismatched with what eBay’s API servers have on hand.

Are reprints of Dracossack, Exciton Knight, and Silent Honor ARK in the works?

From an article posted by The Yugioh Organization,

The Mega Packs are a Best-of set comprised of cards from Lord of the Tachyon Galaxy, Judgment of the Light, Shadow Specters and Legacy of the Valiant. Each Mega Pack contains 16 cards: 1 Secret Rare, 1 Ultra Rare, 1 Super Rare, 1 Rare and 12 Commons

Could this mean that Mecha Phantom Beast Dracossack , Evilswarm Exciton Knight, and/or Number 101: Silent Honor ARK  are about to get a reprint?

It’s still too early to say for certain, but the possibility definitely exists!

We’ll all find out more as the end of August and the release of the 2014 Mega-Tin Mega-Pack draws closer!

Scaling - Fact or Fiction?

image

Scaling (the act of weighing booster packs to determine whether they contain valuable cards) has been seeing a lot of discussion online recently, and so we here at Yugioh Prices thought we would take a crack at it ourselves to see whether or not it really works.

The driving principle behind scaling is the idea that “valuable” cards (i.e. Super Rare, Secret Rare, Ultra Rare, Ultimate Rare, etc.) weigh more than “non-valuable” (Common and Rare) cards do.  So the first thing we needed for our experiment was a scale that was both accurate in its readings, and precise enough in the number of decimal points it measures to in order to successfully determine which booster packs contain valuable cards.

We ended up picking up an American Weigh Scales GEMINI-20 Portable MilliGram Scale on Amazon for $23.64.  The reason why we chose this particular scale was because it was designed for measuring small gems and granulated substances, and it is capable of measuring items as light as 0.001 Grams.

We also picked up 1 Booster Box of Primal Origin, and 5 random booster packs of Abyss Rising from our local Super Target to use as our test subjects.

The process we followed for our experiment was pretty straight forward.

  • We numbered each booster pack individually, and then weighed them two times using our scale.
  • After weighing each pack we concluded that packs number 5, 7, 9, 11, 12, 16, 21, and 23 contained valuable cards, while the remaining booster packs contained worthless commons and rares.
  • We then opened each pack and noted the cards it contained, making sure to take a picture of each for the record.
  • We also performed the same steps for the five booster packs of Abyss Rising we had purchased, and concluded that only one of them likely contained any valuable cards.

The results of all of the weight measurements for each pack we opened, along with whether or not they contained any valuable cards can be found in this PDF file.  We’d post them directly to our blog, but for one reason or another Tumblr just isn’t the ideal platform for uploading scientific data.

In the interest of sharing our conclusions however, we’ve included screen caps of the weight results for booster packs that contain valuable and non-valuable cards

Conclusions

  • Setting aside the moral and ethical aspects of it, Scaling DOES work.  Using our scale we were able to accurately predict which booster packs contained valuable cards, and which booster packs did not.
  • The statistically significant decimal place for determining whether or not a booster pack contains valuable cards is the second one.
  • When scaling booster packs (at least for Primal Origin), you want to find packs that weigh at least 12.35 Grams.
  • The scale that we used for this experiment has a maximum weight capacity of 20 Grams, which is not enough if you plan on Scaling booster packs that are individually packaged in cardboard display cases.  If you plan on Scaling packs like these, we recommend that you use an American Weigh 100g x 0.01g Digital Scale instead.

We are currently experiencing some downtime due to our server’s ISP, but we will be back soon.

And… we’re back!  Sorry folks.
