SELLING BLACK CAT SOFT TOYS CAN EARN MUCH MORE THAN SELLING AK CARDS

Saw a few posts in eBay selling the Mcdonald's Hello Kitty - The Singing Bone at very high price (refer to the postings below).
The prices can be more than S$100K. Imagine if able to sell 10 pcs. can become a millionaire.
AK cards sellers can't become a millionaire even if they sold 1000 cards.
Conclusion is why sell AK cards when you can earn much more by selling the Black Cat without mouth soft toy.
