Which coin has a reeding on the edge?

Could you please clarify which coin you are referring to in this context? It's not uncommon for some coins, especially those of higher denominations or those with a historical significance, to have a reeding or ridge pattern along the edge. However, this feature is not exclusive to any one particular cryptocurrency coin as it's more of a physical security feature found on traditional coins. If you're asking about a specific cryptocurrency coin or token that is represented as a physical object with a reeding on the edge, it's important to note that most cryptocurrencies exist solely as digital assets and don't have a physical form. Some companies or organizations may produce physical coins or tokens as a novelty item or collector's item, but these are not typically used for transactions and don't have the same value or functionality as the underlying cryptocurrency. So, in short, the answer to your question depends on the specific context and what you mean by "coin" and "reeding on the edge." If you're asking about a traditional coin, there are many examples that have this feature. If you're asking about a cryptocurrency coin, it's less likely that it would have a physical form with a reeding on the edge.
