Pokemon that are very rarely sold, such as shiny megas or shiny
legends, do not have. a fixed price. If you look at the stagnant
line of the market insider graph, it shows that almost no reliable
sales has been made. Therefore, all sale values are determined by
the buy-seller negociations. However, if you want a price estimate,
shiny legends prices normally hover over around or under the price
of 40 of it’s summons. Therefore, assuming star pieces is valued at
around 20k pd per piece, shiny jirachi would be valued at 5 x 20000
x 40 = 4 mil pd. even so, that’s still a estimate, as star piece
values has been seen to be dropping recently.
