Does anyone know how many there are in the full set? Being 'Wonders of the World' I'd guess seven different?

I got a few in a deceased estate lot I bought recently, and the leaflet in the classy little black presentation box does not mention how many there were - just all the detail about the one in each box. This person had a few different designs.

The only thing I could find looking on ebay was this one for sale ex SIN for $US35, which gives some detail on the content and maker etc.

Not sure what "400 grains" of silver is in ounces, but they are pretty solid! :

Wish all airlines came up with classy little souvenirs like this for pointy end long haul. I am doing a lot of KLM long flights next week and those little blue Delft pottery houses filled with booze are a fantastic giveaway that are always popular with pax. ^
