What is a mint mark on a coin?
Could you please elaborate on the significance and purpose of a mint mark on a coin? I'm particularly interested in understanding how it relates to the authenticity, value, and provenance of a coin. Do all coins feature a mint mark? If not, what determines its inclusion? Are there any specific characteristics I should look for in a mint mark to authenticate a coin? Additionally, how does a mint mark differ from other markings on a coin, and how does it affect the coin's collectibility? Thank you for your insight on this topic.

Could you please elaborate on why Coinbase decides to put a hold on users' balances? I've recently noticed this happening with my account and I'm curious about the reasons behind this practice. Is it a standard security measure or are there specific factors that trigger this action? I'm particularly interested in understanding if this is a common occurrence and what steps Coinbase takes to ensure that the holds are justified and lifted as soon as possible.

Does universalcoin have a physical address?
As a keen observer of the <a href="https://www.btcc.com/en-US" title="cryptocurrency">cryptocurrency</a> landscape, I'm curious to know if UniversalCoin, a relatively new entrant in the digital currency sphere, maintains a physical address. Given the decentralized nature of many cryptocurrencies, it's not uncommon for projects to operate primarily in the digital realm. However, having a physical address can often provide a sense of legitimacy and trustworthiness, especially for investors and potential partners. So, I'm wondering, does UniversalCoin have a physical address where it conducts its business operations, or does it rely solely on digital means of communication and transactions?
