Hi Hannah,

Thank you for contacting Mearto with your appraisal inquiry.
So few people use sewing machines these days that the market is somewhat flooded by them; with considerably less demand than supply, prices remain modest with most models by Singer - the gold-standard in sewing machines - bring less than $200. Ones that are not built into tables and retain their original domed cases - yours meets both of these criteria - are worth more: $400-500. (You may be interested to know that the record price for a sewing machine by any maker is $41,000, realized for a Singer example that also doubled as a grandfather clock, see here: https://www.liveauctioneers.com/item/50643796_monumental-unique-singer-sewing-co-bronze-master-clock)
If you'd like your appraisal to include dimensions, which is customary, please send me the height, width and depth of the box and I'll update ASAP.
