None at the moment. You would have to work out your own system, one that wouldn't make doing so tedious.
I would start with weapons and armours.
You could start with hardness and how many hitpoint a item has and give out tokens to each player to represent the hardness & hitpoints (see p158 PHB - sunder rules)
ie Longsword would have 15 (hardness+HPs)
After each battle if the player was involved in combat ask them to give you a 1 weapon token.
Armour is a bit tricker, you have hardness, but hit point are worked out on page 166 table 9-9. You will probably have to make your own table. Same as weapons, if the player got hit during the battle, then the player hands you 1 armour token.
The issue with all this is that the rules allow Adamantine to cut through anything, but when your in a fight it does 0 damage to armor, when in theory it should be cutting it to shreads.
Its a start (im sure with plenty of if and buts), if you go with my idea and flesh it out and improve it, I would be interest in what you end up with and how it plays out in your campaign
All the best
