Game corner prize... only if it were on the lower end of 1,500 - 2,500 coins.
9999? Get out.
I honestly think $250,000 would be fair. Anywhere between $250,000 and $500,000 would be ideal.
$1,000,000 is just silly.
[spoiler]For the record I own 2 Amnesia Brace.
I personally wouln't feel ripped off if the price was $250,000 poke$$$[/spoiler]
