The value of red rose tea figurines, like all other collectibles, depends on the availability and demand of collectors. Collectors mostly look for figurines from the earlier series and pieces without flaws and cracks. So, they may be willing to pay for the "perfect" pieces over time.
After each series is closed out, availability is limited to trading among collectors. The early figurines being hand painted have differing decorations. These figurines are highly collectible and in great demand by collectors. More variations were added to the figurines due to new production methods. These have inadvertently increased the collectible value of the figurines.
