In 1964, a humble antiques dealer spent £5 on a crusty old chess piece, put it a drawer and promptly forgot about it.

It turns out this battered warrior is part of a famous medieval chess set that had been missing for almost 200 years. This £5 purchase has just a sold at auction for £735,000, or $1.3m.

The piece is part of a set known as the Lewis Chessmen that was made from walrus ivory in the late 12th or early 13th century.

But after looking after it for more than 50 years (or rather didn’t know it existed) the antiques dealer’s family were “quite amazed” by its value.

And speaking of surprise valuables:

ASX small cap winners: July 1-5

NeuroScientific Biopharmaceuticals (ASX:NSB) was up 124 per cent for the week after claiming an Alzheimer’s breakthrough.

The company’s EmtinB drug demonstrated the “largest ever improvement in neurite growth and increased number of active connections between nerve cells”, it says.

NSB shares went on a massive tear, up as much as 186 per cent to 40c on the news. However, trials are only at the pre-clinical stage, with in-human trials “to be initiated this quarter”.

In May, (very) diverse micro-cap explorer Greenpower Energy (ASX:GPP) entered an agreement to potentially buy the historic gold mines of Camel Creek, Golden Cup and Big Rush in Northern Queensland

On Thursday, it announced a very handy near-surface exploration target of 32,154oz-112,540oz of gold at the Camel Creek mine – which sent the stock up 111 per cent.

Medtech play Medibio (ASX:MEB) climbed over 110 per cent after signing on British food service conglomerate Compass Group to the pilot program for its corporate mental health app, ilumen.

Kyckr (ASX:KYK) also scored a commercial partnership with the Singapore division of global insurer AXA Insurance, sending the regtech stock up 97 per cent for the week.

And shares in internet-of-things company Connected IO (ASX:CIO)  got a boost after it announced a new personal best for quarterly cash receipts.

ASX small cap losers: July 1-5

SpeedCast International (ASX:SDA) took another massive hit following an earnings cut.

It blamed a raft of reasons from NBN delays, customer churn in one industry, technical problems with a big contract, and social unrest in Mozambique.

At $1.80 a share, it has lost 73 per cent since late August 2018 (when it was $6.65). Ouch.
