I have a nearly complete Monopoly set that I've been researching, and some dates I found tossed around are 1947 and 1955 (on selling pages), but I still can't even confirm the decade it was made. Here are the details of my set:
BOX:
Similar to this picture (taken from here) - but the border and sides are red, not white, and the bottom text is
- PROPERTY TRADING BOARD GAME [black text]
- Manufactured in N.Z. by [red]
- THOS. HOLDSWORTH & SONS LTD.
- LONDON & LEEDS
- Another HOLDSON Product
BOARD:
Bright green, with "TRADE MARK 711981" written below the logo
CARDS/MONEY:
Chance and Community Chest cards have rounded corners, no pictures, and the Chance cards are more pinkish than orange or red. Money colours are: yellow ($1), light blue ($5), greyish blue ($10), green ($20), pink ($50), yellow-orange ($100), red-orange ($500). Title Deeds: the mortgage side is red text, and my set has the error described here where the '1 house' rent for the last yellow property is $120 instead of $110 like the other two cards.
PIECES: Houses/hotels are wooden, with houses being smaller and green, hotels red. Dice are plastic, red with white dots. My 6 tokens are plastic cone-like things with thin tops and round bases.
I'm sure this is enough information to come up with some possible years, I just can't find them! Thanks in advance for any input on this :)
EDIT: I can't find a copyright year anywhere but I found at the bottom of the rules it says "W. & H. LTD. - 13288"
