The measured specifications of this coin align with Gae-won-tong-bo coins excavated from the Goryeo Dynasty. As shown in the photographs, this is an unearthed coin.

It exhibits characteristics such as a narrow rim and similar script styles, as documented in historical catalogs.

While historical records like the Goryeo Sa mention coins such as Geon-won-jung-bo and Dong-guk-tong-bo in detail, there are no explicit records for the Goryeo Gae-won-tong-bo. However, it is listed in catalogs, and Gae-won-tong-bo coins that differ significantly from Tang Dynasty standards (smaller in size, with narrow rims and crude script) are continuously being discovered in tombs and historical sites.

It is plausible that the name Gae-won-tong-bo was borrowed to promote the early Goryeo monetary economy after the fall of the Tang Dynasty. This is supported by the differences in script and specifications compared to Chinese, Japanese, and Southeast Asian Gae-won-tong-bo coins.

**Possibility of a Special Votive Coin:**
Given its unique characteristics, such as the white copper alloy of this coin, it is highly probable that this was a high-quality Goryeo coin produced in small quantities for royal bestowal or ritual purposes, rather than for general circulation.
