Royal Albert collector plate 'Elizabeth of Glamis' (not authenticated)

This is a circular ceramic collector plate made of fine English bone china, presented with a white background and deep reddish-purple (magenta or mulberry) text and decorative border graphics printed on the reverse side. The reverse features extensive maker information and descriptive text printed centrally in a mix of serif and script fonts. At the very top, a crown graphic appears above the text 'ROYAL ALBERT' with a registered trademark symbol. Below this, on the left, it reads 'BRADEX No: 26-R64-1.1', and on the right, '1990'. In the upper central area, it reads 'Plate No: 1471M'. Prominently displayed in large script is the title ''Elizabeth of Glamis'', followed by 'by Sara Anne Schofield'. Additional centered text reads 'Original artwork commissioned exclusively for the first issue in the collector's plate series The Queen Mother's Favourite Flowers', followed by 'Produced in fine English bone china in an edition strictly limited to a maximum of 150 firing days'. At the bottom, a decorative crest featuring a crown and monogram emblem sits within a scrolling vine border that frames the entire text block. The physical condition appears clean and well-preserved based on the crispness of the printing, with no visible cracks, chips, or staining on the reverse surface shown. The attribution relies entirely on the clearly legible printed maker's marks, brand name, artist name, and production details visible on the back of the plate, though these markings remain unauthenticated.

Based on what I can see in the photograph, the item bears printed markings consistent with a Royal Albert collector plate titled 'Elizabeth of Glamis' from 'The Queen Mother's Favourite Flowers' series, attributed to artist Sara Anne Schofield and dated 1990. The reverse shows crisp magenta text, a Bradex number, and a limited edition firing day notice, all suggesting fine English bone china manufacture. The physical condition appears well-preserved, showing no visible cracks or chips on the surface displayed. However, I cannot verify from a photo alone whether the markings are contemporary or if the plate is a later replica, copy, or commercial reproduction. Collector plates of this era and type generally experience modest secondary market demand, typically trading within the $20 to $45 range when found in good condition. If physical inspection were to reveal that this is a reproduction or not produced by Royal Albert, the value would likely drop to nominal decorative worth of under $15. To establish a more precise valuation and evaluate authenticity, an in-person examination by a ceramics expert, physical inspection of the glaze and paste quality, and checks against official manufacturing records would be required.
