From your post….i dont know your full conversation with the lady or lady's daughter, whatever you have written when you write ….you are going to have a lot more by her….(not just the blue jacket ) may also mean blessings and memories.
What there a contract or commitment by the lady or her family with you for some payment to you before the lady passed away and was not fulfilled ?
The line you wrote does not necessarily mean money or materials….it could mean non material things also….which are just priceless and yet valued.
