Mr Corker contacted police on November 15 after discovering half a dozen antique silver and crystal pieces, some dating back more than 200 years, were missing from his house about 10.30pm.
He told the Courier that the pieces, passed down through generations of his family, were kept in foam boxes in a locked room.
The pieces were estimated to be worth $35,000-$45,000.

READ NOW‘I woke up one morning and realised that one of the pieces had gone missing; it didn’t take long before I realised they had all been stolen except one piece,’ Mr Corker said.
‘I have been through some hard times in my life but I could never sell these pieces because they meant so much to my family, so now in a way, I feel like I have let down my mother, who left these with me.
‘Despite this being a very expensive loss, it is more of an emotional loss because I had planned to pass these down to my daughter and now I won’t be able to do that.’
Mr Corker said that seven pieces had been stolen and he hoped that the community would be able to help to locate the family heirloom.
Kwinana police station Sergeant Simon Nichols is urging anyone will any information about the whereabouts of the pieces to call Crime Stoppers on 1800 333 000.
