How to preserve 46 year old peanut ornament?

My mom made Mr Peanut as a Christmas ornament in 1978 and he had been a cherished member of our family ever since! Unfortunately, he is starting to show his age and he officially retired from Christmas tree duty this year! We’d love to know the best way to preserve him but I’m so scared to mess him up! Any tips or ideas would be so greatly appreciated! Let’s give Mr Peanut a second life!
