Presumptive Republican presidential nominee Donald Trump's campaign is running a wee bit low on cash. 

The candidate's war chest held just $1.3 million at the start of June, compared with the $42 million held by presumptive Democratic nominee Hillary Clinton.

And for a guy who likes to boast, $1.3 million is not the kind of money that the billionaire real estate mogul wants to boast about. That's because it's not nearly enough to finance a traditional presidential campaign -- though, in his defense, Trump's campaign is by no means traditional.

It certainly won't be enough to keep up with the advertisements Clinton is likely to continue to buy. 

In fact, it's not enough money for a lot of things. Just for funsies, here's a list of some of those things below. 

1. Lunch with Warren Buffett

Trump's a billionaire, and so is businessman and investor Warren Buffett. They could probably figure out a lunch date if they wanted to. But Trump's campaign funds wouldn't have bought him a sit-down with Buffett in 2010. 

At that time, Buffett auctioned a lunch with himself for $2.63 million, sold to an anonymous man and his seven buddies. (Proceeds went to the Glide Foundation in San Francisco.)

2. The comic that introduced Superman

Superman came into the world in June 1938, as part of an issue of Action Comics. 

That issue is now worth $1.5 million, or $200,000 more than the amount of cash inside the Trump campaign coffers.

3. Rhino horn cups

In July 2011, Antiques Roadshowfeatured a set of cups carved from rhinoceros horn. Valued at up to $1.5 million, they were the most expensive item to ever appear on the show.

At the high end of their value, these cups would also be well out of reach. Trump's campaign will have to find something else to hold his morning beverage. 

4. A 1909 Honus Wagner baseball card

Honus Wagner may not be the household name that Babe Ruth is, but Wagner's career with the Pittsburgh Pirates earned him one of the first five spots in the Baseball Hall of Fame. 

Wagner's 1909 baseball card is also super rare because its production ceased when he discovered that the American Tobacco Company had started making them without his consent. Wagner didn't want kids to buy tobacco. 

Only around 50 of these exist, and one of them sold for $2.1 million at auction in 2013. 

5. The violin that played on the Titanic

The violin that reportedly played in April 1912 as the Titanic sank sold for $1.7 million in 2013. 

What's still affordable

There are plenty of things Trump's trim campaign stash can afford, but it's not like $1.3 million is chump change. 

The campaign could still, for example, buy 26,000 pounds of steak from Trump Steaks if they needed it for campaign dinners, although it doesn't appear the amount of meat sold by Trump Steaks ever came close to that number. 

Or if a single campaign staffer needed new digs, they could use that amount of campaign cash to stay in an executive park-view, one-bedroom suite at Trump International Hotel in New York City for nearly three years. 

In case Trump would like to use his money for something more presidential, though, his campaign will probably need more dollar bills. 

This is something he clearly knows. On Tuesday, the campaign sent out its very first fundraising email. 

This Tweet is currently unavailable. It might be loading or has been removed.

In it, Trump promised to "make it the most successful introductory fundraising email in modern political history by personallymatching every dollar that comes in within the next 48 hours, up to $2 million!"
