According to Variety, the theft recently occurred in a lorry park in Mexborough in Yorkshire, England, while the production was filming nearby.
The heist is not expected to affect production on the upcoming series, and Netflix officials hope to retrieve the stolen goods.
"We can confirm the antiques have been stolen and we hope that they are found and returned safely. Replacements will be sourced, there is no expectation that filming will be held up.".
To help recover the items, members of the production gave a description of some of their props to the weekly publication Antiques Trade Gazette.
