Thanks so far guys, the challenge is that I can't seem to find a typical Greek or Roman point. Similar styles of points were used many combatants at the same time. Arrows being somewhat disposable, you fire it and forget it until it's fired back at you by your opponent. There seems to be a merging of designs. Add in points of different ages and the typology of projectile points becomes quite complex.
Searching eBay and Google I do find similar styles, some new and some said to be 1000 BC but no definitive classifications. I'm sure there are some knowledgeable collectors on eBay but most seem to have little understanding of the cultures and times that their wares attempt to represent.
Another challenge is that many of these points may actually be currency or votive offerings rather than actually intended to be short from a bow. The more ornate points are in this class, the design, weight and manufacture being too labour intensive to warrant them as disposable.
In geographic terms there are some areas where there was not a high degree of cultural mixing (Japan), I don't see as much confusion as to doppelganger designs for battle use. There are specific point designs for specific uses - battle points, indoor points, points for birds, small animals and votive objects etc. There are a multitude of designs but it seems that Japanese points are largely dissimilar to say Chinese or Persian/Greek points although there are unique designs for the same purposes as those in Japan. I'll post some Japanese points shortly, there seem to be thousands of designs only limited by the artistry of their makers, the majority being too impracticable to be used as "arrows". I don't know enough about Japanese culture to be sure but I believe votive points were given to guests during special holidays as a symbol of good luck or as a degree of esteem.
The material that the points are made of is also a defining attribute of where these points come from. In areas where there was ready supplies of iron ore you may see points made of iron in other areas where copper and tin is more availible you would see weapons made of copper or bronze. The materials and modes of construction also change as metal-working technology changed or as new trade routes opened up allowing access to the raw materials, technology and immigration of skilled workforces. These and many more criteria would aid in defining as to when, where and what culture projectile points represent. I see a similar set of criterial for numismatics which is why while I'm interested in old coins but don't collect them - projectile points seem more cool.
Reproductions are everywhere, my fathers points
seem legit, my Japanese points - I don't think so
. I have others that are so primitive that they could be 1000 or 1 year old. Reproductions of Japanese votive points are made by many companies in China who make Japanese swords and exhibit the fake or real hardened edge of Samurai swords. I'll get busy with my camera and post some more points shortly.
