How do you check my educational certificate fake or original?

i've passed my 10th from i.c.s.e board in 1995-96, and i've misplaced my original marksheet.

so can i have a duplicate of my mark sheet.

waitig for your reply, as soon as i get your reply i'll mail you my details (i.e. hall ticke no & other details.)

i misplased it when i was taking all my certificates to the Xerox shop. So i request u to please guide me in this request.
