Daicos? plus a couple more q's

[seshquatch]

Just saw a Josh Daicos Bang numbered 101 go for 185 dollars on ebay? Why so much? Is there something I'm missing?
Ive been collecting afl cards since i was a kid back in 06, but hadnt got a pack of cards for like 3 years since this year, and am getting back into it. So ive got an odd question or two like the one above.
Whys eddie betts 2020 wildcard so much aswell?
Lightning Bursts seem to sell for pretty low considering theyre 1 in 72.
Ive only seen one since i started getting into footy cards a few weeks ago, but where are all the petracca brownlows? ofcourse i know theyd be pretty hot right now, id love to find one as a dees fan. How much would one be worth currently roughly.
Sorry for all the random questions, thanks.

believe it's an error card, with Daicos spelt 'Diacos'
& the Collingwood tax

Error card and fact it can be sent back for replacement means it will be essentially halfed in numbers with 50% redeemed and 50% not (or whatever break down it ends up at).

Collingwood fans now all need 2 daicos to fill set and yet the amount has not increased.
