Technology to replace subjectivity for collectibles grading

Counterfeits are increasingly sophisticated and many claim there are inherent flaws in the current collectibles grading system- but no coin in the world can fool us!

Our technology extracts a treasure trove of data, including 7,000,000 individual laser measured height and 23 million laser measured color data points.

Our digital fingerprinting and advanced grading reports virtually eliminate the risk of counterfeiting by providing a level of detailed analysis based on extremely precise physical, measured data that supports the assigned grade.

Our filed & pending patents backing the first marketplace of its kind

We integrate nano-level grading, pre- and post- sale authentication, and a smartphone/blockchain/smart contract application - with shared royalties earned on re-sales.

By integrating these technologies, a new era of authentication, engagement, and value preservation is dawning for numismatic and collectibles.

Join the future of
collectible grading.

Frequently Asked Questions

Why invest in startups?

Crowdfunding allows investors to support startups and early-growth companies that they are passionate about. This is different from helping a company raise money on Kickstarter. With Regulation CF Offerings, you aren’t buying products or merch. You are buying a piece of a company and helping it grow.

What types of securities can I buy on this site?

The majority of offerings are common stock, though some companies may raise capital through convertible note, debt, and revenue share.

How much can I invest?

Investors other than accredited investors are limited in the amounts they are allowed to invest in all Regulation Crowdfunding offerings (on this site and elsewhere) over the course of a 12-month period: If either of an investor’s annual income or net worth is less than $124,000, then the investor’s investment limit $2,500, or 5 percent of the greater of the investor’s annual income or net worth, whichever is greater. If both an investor’s annual income and net worth are $124,000 or higher, then the investor’s limit is 10 percent of the greater of their annual income or net worth, or $124,000 whichever is greater. Accredited investors are not limited in the amount they can invest.

How do I calculate my net worth?

Calculating net worth involves adding up all your assets and subtracting all your liabilities. The resulting sum is your net worth.

What are the tax implications of an equity crowdfunding investment?

We cannot give tax advice, and we encourage you to talk with your accountant or tax advisor before making an investment.

Who can invest in a Regulation CF Offering?

Individuals over 18 years of age can invest.

What do I need to know about early-stage investing? Are these investments risky?

Ref CF Offerings are high risk opportunities and may not retain their value. Investing in startups and small businesses is inherently risky and standard company risk factors such as execution and strategy risk are often magnified at the early stages of a company. In the event that a company goes out of business, your ownership interest could lose all value. Furthermore, private investments in startup companies are illiquid instruments that typically take up to five and seven years (if ever) before an exit via acquisition, IPO, etc.

When will I get my investment back?

The Common Stock (the “Shares”) of Coin and Card Auctions, INC. (the “Company”) are not publicly traded. As a result, the shares cannot be easily traded or sold. As an investor in a private company, you typically look to receive a return on your investment under the following  scenarios: The Company gets acquired by another company. The Company goes public (makes an initial public offering). In those instances, you receive your pro-rata share of the distributions that occur, in the case of acquisition, or you can sell your shares on an exchange. These are both considered long-term exits, taking approximately 5-10 years (and often longer) to see the possibility for an exit.  It can sometimes take years to build companies. Sometimes there will not be any return, as a result of business failure.

What if I change my mind about investing?

You can cancel your investment at any time, for any reason, until 48 hours prior to a closing occurring. If you’ve already funded your investment and your funds are in escrow, your funds will be promptly refunded to you upon cancellation. To submit a request to cancel your investment please

How do I keep up with how the company is doing?

At a minimum, the company will be filing with the SEC and posting on it’s website an annual report, along with certified financial statements.  Those should be available 120 days after the fiscal year end.  If the company meets a reporting exception, or eventually has to file more reported information to the SEC, the reporting described above may end. If these reports end, you may not continually have current financial information about the company.

What relationship does the company have with DealMaker Securities?

Once an offering ends, the company may continue its relationship with DealMaker Securities for additional offerings in the future.  DealMaker Securities’ affiliates may also provide ongoing services to the company. There is no guarantee any services will continue after the offering ends.

Can I sell my shares?

Shares sold via Regulation Crowdfunding offerings have a one-year lock up period before those shares can be sold freely. Exceptions to limitations on selling shares during the one-year lock up are transfers:
-to the company that issued the securities;
-to an accredited investor;
-to a family member (defined as a child, stepchild, grandchild, parent, -stepparent, grandparent, spouse or spousal equivalent, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law,-including adoptive relationships.); in connection with your death or divorce or other similar circumstance;

What happens if a company does not reach their funding goal?

If a company does not reach their minimum funding goal, all funds will be returned to the investors after the closing of their offering.

How can I learn more about a company’s offering?

All available financial information can be found on the offering pages for the company’s Regulation Crowdfunding offering.

Can I cancel my investment?

You may cancel your investment at any time, for any reason until 48 hours prior to a closing occurring.  If you have already funded your investment and your funds are in escrow, your funds will be promptly refunded to you upon cancellation.  To submit a request to cancel your investment please email
