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:
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
Bright green, with "TRADE MARK 711981" written below the logo
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"
