Card Of The Week January 13

BBM started including insert cards called "Phantom" with their team sets in 2017.  These were very limited edition inserts that were serially numbered to 25 each.  Each team set had between 6 and 18 of these and they featured active players from the team.  BBM continued having them with their team sets in 2018 and also added 12 "Phantom" inserts of OB players to their Fusion set in November.

I got curious about these cards and ended up getting one relatively cheaply on Ebay.  It's for Tetsuya Yamaguchi of the Giants and I think it ran me $10 or less.  Here's the front and back of it:

You can take a quick look at this search on Yahoo! Japan Auctions to see what these cards are selling for.  At the time I did the search the cheapest was Sho Nakata's 2018 card which was only 1000 yen while the most expensive was Shohei Ohtani's card from last year (and apparently has serial number 01) which is priced at 30,000 yen (about $275).  Most appear to be in the 3000 to 5000 yen range.
