What year is a Hero pen considered an old model?

616 and 329 are iridium pens, and the year or year of production can only be determined from the characteristics of the pen or the packaging box.

100 and 200 are 14k gold nib pens with the year represented by letters engraved on the nib.

Generally speaking, old production is better than current production.

However, the inventory of old products is running low and prices are high.

In terms of gold tip pens, 2002 can be regarded as an old product.

Iridium nib pens have been around since at least the 1990s.
