Hi Gary
I collect Chubb of all descriptions, and follow the market closely…
I’ve learnt that, regardless of what we think of the items in our collections, they’re worth what the last one sold for, really. Market dictates…
That padlock was bid on yesterday, on eBay. Attracted 45 bids, top bid being US$1,825.
Alas, that lock is worth, at the very least, US$1000. Bearing in mind its original key, I’d say it’d be worth pretty much the $1800 someone bid.
The typical brass Chubb padlock is rather common. However, the Chubb’s of that close-shackle sort and size are getting very rare. The few I have seen have sell, over the last few years, have been close to, or above, US$1000.
Supporting the value, I have one the same size as that in question, but at least twice as old. Bought it a year ago for about US$900. Was able to get the price down due to the key bow being non-original (though still well made).
Most of the locks that size, including mine, are ex-Government Armoury locks.
Hope that helps.
