Quoted from ThePinCollector:You may see more Marilyn for sale in the us since they were the early release.Once production ramps up they ship a sh#t ton oversees and those hardly come back or show up for sale.From what I understand there are less than 5% max are Marilyn, its documented pretty widely. just for now those come up for sale more often.
I think the "documentation" was less factual and more downplaying the potential legal issue of using Marilyn's name. If you check out the serial # database info, it suggests that over 1,000 Marilyn models were made for the US and over 1,000 were shipped internationally. Quantity produced is unknown, but if the serial #s are sequential (which is not always the case) then over 8,400 total were produced. I would estimate at least 25% of Taxi machines were Marilyn models, and it could be more.
I'll post to the Taxi owner's club and ask them to add their machines to the database, and maybe with more data we can get a clearer answer to this age old question! The database is here:
