Heirloom, Indiana
Seen almost as often as the Harvest pattern, Indiana's Heirloom is their version of a cut-style pattern. Mostly seen in red but occasionally in purple. I suspect the molds came from a variety of sources as the details vary between the different shapes. None of the pieces is marked. Prices below are based on ebay sales--the best place to trade this pattern. Be aware that the price range I give is for the middle of the selling range. A little careful shopping can usually get you a better price.
Bowls or center bowls
Usually sell in the $20 to $30 range but can be found for under $15.
A red banana boat sold in 2019 for $25.
A purple deep round bowl sold in 2022 for $25.
Rosebowls
Expect to pay $15 to $25 for these, although the red one above, with blue iridescence, sold for $110 In 2022.
Water pitchers
Heirloom pitchers are often referred to a Octagon Variant, though they are not Imperial's pattern. Simply a matter of ignorance. Pitchers in red sell in the $25 to $40 range, purple a bit more.
Vases
These are usually swung out to 10 or 11 inches. Mostly in red, they sell for about $20, though you can pay less or quite a bit more.
Plate (back shown)
Originally offered in combination with the bowl as a Dessert Set, the 12-inch plate is usually found individually for $35 to $50.
Baskets
Found in two styles, one looking more like a bowl with a handle and this one. Either bring $25 to $40.
Water set
When this red set sold in 2022, it was listed as Sunset. Clearly, it's this same Heirloom pattern. It brought $150..

Punch set

Sugar and creamer, butter dish
The creamer and sugar bowl were sold as a set; the butter dish was sold separately. Creamer and sugar sets sell in the $20 to $30 range; the butter dish by itself about the same, but a butter and sugar sold on eBay in 2008 for $53, though a set as above sold for just $20.

Other shapes
Console sets were made up of 2 small candle holders and a bowl. Quite rare, one of these sold in September 2003 for $93.
Also known are goblets and tumblers.
