Lost Expired Passport. Will this affect H1B Stamping process?

My H1B petition was recently approved and all that is pending is the stamping/interview process. Looking at the documents required, it says that “Along with passport, all old passports held should also be taken along”. My old passport expired in 2010 and currently own a new one. I have recently lost the expired passports . Is this going to be a problem during the stamping process? Do you think it’s wise to report this as lost to police and get an acknowledgement from them?

Appreciate your responses.

Thank you

I have the same question. Please let me know if you were able to get H1B stamped?
