Antique trunk

I have an old large flat top wooden trunk, Iv had it for about 35 years, it's really nice but does have some cracks in the top and bottom but it is very solid...  I believe it to be 200 to 300 hundred years old .. It has very old hardware on it with nails that are extremely old ...  I have a few pics I just took at a moments notice but I can clean the stuff I have setting on it and move it for better pics...  The inside and backside has a lot of oxidation and been very oxide....  It's very old and I know nothing about it but it sit in my grandparents front entry way and I inherited even though my dad threw a fit when I moved out on my own with it ....  Can anybody help me and give me a good appraisal on it
