Yes, despite the difference in weight and diameter I also think it's KM# 130. It's a pity the regnal year is a bit out of flan but it looks like it is 20:
I don't think the second digit can't be anything else than a 0. The first digit could be a 3 but regnal year 30 doesn't exist, so I go for regnal year 20. Can you agree on that
