According to this article from 2014, the cost to buy the entire LEGO® Star Wars collection since 1999 would have been just under $15,000 USD ($14,762). I assume the price mentioned in this article is calculated based on original MSRP, not inflated resale or in-store sale values.
Using MSRP as the baseline for all sets across time, what would the current sum total be of the entire Star Wars licensed collection?
