PHS Committee Member Carolyn Clark tells me:
Plastics prices for the unusual and rare at auction have been holding their prices.  Although the bakelite coffin failed to sell last year, other lots have achieved high prices.  In a recent sale, the Master Incolor Cocktail Shaker in cream urea formaldehyde (incorrectly described as bakelite and carrying an estimate of £40-£60 in the catalogue)  made £360, plus buyer’s premium.

Even the basic pieces can still attract a good price.  A Carvacraft photo frame in butterscotch has just sold on Ebay for £123.25 following 18 bids and a calender in the same range for $177 (about £110).
