You need to contact your mobile phone provider directly rather than the police, the police cannot assist in this matter. Your phone provider may be able to send you a new SIM card. You can go into the phone store of your provider, they should be able to either deal with your problem themselves or refer you on to customer services. They may speak to customer services for you if you ask.
Different phone providers will have different policies on issuing a replacement SIM. Some may send a new one out free of charge. However, others may charge a fixed amount, if this is the case though it should only be a small amount. You could write directly to your phone provider explaining what the issue is. Although this is likely to take longer, writing a letter formally shows that you are serious and that you care enough to go to this amount of effort. Also it allows them to deal with the issue without it being confrontational.
The other option is to buy a new SIM that will work with your current contract if you have one. Your phone provider will be able to advise you on which one to get. If there is any danger of details being lost then you should be able to either save them to the phone itself, your computer or your phone store should be able to back up the information for you. Phone providers will often be able to send multiple SIM cards in case of loss so there will always be extra available in case of an emergency.
