8 of the Most Valuable Kinds of Pressed Glass

3) Vaseline Glass

This type of glass gets its nickname from its unique translucent petroleum jelly color. The yellow-ish tint comes from the addition of uranium oxidewhile in the molten state. Production dates for the most vibrant pieces range from the 1880s to the 1950s. After 1958 only depleted uranium was used in the production process, which resulted in a different color. Today, prices can vary wildly, but more elaborate pieces and sets can sell for upwards of $1,000!

2) Custard Glass

Like Vaseline glass, custard glass has a yellowish cast from uranium. However, this opaque glass was often made in different styles from Vaseline glass. The pieces from the 1930s, like salt and pepper shakers and rolling pins, are styled much more like their contemporary Jadeite counterparts. However, custard glass was in production from the 1890s, long before Jadeite.

Serving pieces, vanity sets, and kitchen items made of custard glass can sell for $20-$300 depending on rarity. Beware though, there have been many reproductions made over the years!
