Ancient numismatic craft technology has really advanced by leaps and bounds. This beautiful is amazing. In fact, I found that blue rust fraud is the most difficult to identify.

The reason why ancient numismatic crafts are rust-colored technology has advanced by leaps and bounds. There are two reasons for this.

1. This has a lot to do with those rating agencies: your genuine coins are fake rust, which does not affect the rating, and can get a high score, so naturally people will study and evolve the rust color.

2. It has a lot to do with the collector's excessive pursuit of the rusty color of the coins.

In short, the road to collecting ancient coins has a long way to go.
