From the point of views of someone who monthly earned 58’746 yen (tax included) in his previous life, someone possessing several platinum plates appeared to be plenty rich. (E: ~$488, which is hard to believe considering that is less than my cheapest apt rent ever)
There were many people in this country who wouldn’t get to see something like a platinum plate until their death.
The people having seen something like a platinum plate within his home territory were zero including his father who was a noble.
