Repossession Houses

Have tried the local paper but can’t find any information there. Does anyone know if there’s a website that lists auction houses? I’m in Hertfordshire in the UK.

Im looking for auction houses that ideally specifically deal in Sporting memorabilia but if not then somewhere that does sell sporting memorabilia
if it helps what im looking to sell or at least get valued are signed football shirts with certificates of authenticity and motor sport memorabilia again with COA’s

anyone who can tell me anywhere that deals in sporting memorabilia is much appreciated

thanks

Anyone know of any auction houses near to romford, thanks in advance

Have stuff to sell off, like old transformers, Lego’s, Centurion comics, and crystal ornaments. I know people say Ebay - but are there other auction sites? Where do i look for auction houses or places to sell things?
