The Chinese factories have made some good quality paperweights in the past - and many millions of low quality ones. That trend continues today.
Below are some images from recent catalogues: these paperweights typically cost from 30p to £3.00 per piece ($0.50 to $8.00) when purchased by the crate. The cheaper ones often turn up in petrol station shops in the UK, costing £4.99 to £9.99. The skill and workmanship often makes them good value for money when offered for sale for a few £s, but caveat emptor.....they sometimes turn up as antiques, with antique prices!
