I stumbled on this "high end antiques" site called 1stdibs and oh man do you want to see some stupid prices on pinball machines? Check these out! (prices in USD)
$5000 for a Bally Viking? https://www.1stdibs.com/furniture/more-furniture-collectibles/collectibles-curiosities/games/bally-viking-pinball-1980/id-f_12691871/
$6780 for a Bally Firecracker. https://www.1stdibs.com/furniture/folk-art/toys/mid-century-modern-german-pinball-machine-firecracker-art-jerry-kelly-1971/id-f_13063472/

Still have money to burn?
$29,000 for a Data East Star Wars https://www.1stdibs.com/furniture/more-furniture-collectibles/collectibles-curiosities/games/pinball-stars-wars-data-east-manufacturing-1992-collector/id-f_4413533/
Match it with a $26,000 ball bowler... https://www.1stdibs.com/furniture/more-furniture-collectibles/collectibles-curiosities/games/1962-royal-crown-vintage-indoor-bowling-alley/id-f_14644302/
The most disgusting thing of all I found there has to be this atrocious pachinko table for $1150... https://www.1stdibs.com/furniture/tables/side-tables/custom-pachinko-game-coffee-table-rehab-vintage-interiors/id-f_9737403/ I actually have that same machine in my basement, it's worth about $80, and all they've done is lay it on a metal frame.
Since it's an antique site I did search for "bagatelles" and they at least had some good reference photos of bagatelle types, though these same tables sit unsold on ebay for a fifth of the price.
