Belper Town, facing an organised and well-drilled side, couldn’t provide enough quality on the ball in their friendly defeat.
Sam Colbear was an important absentee from the starting 11.
However, manager Grant Black’s selection criteria is slowly defining the shape of his team that will start the Evo-Stik East Division One campaign on 18th August.
Coalville, who will play in the Evo-Stik South Premier Division next season, were always going to give the Nailers an exacting 90 minutes, although Belper started well.
Nathan Curtis tested Max Varnum with a fierce shot from the edge of the area after four minutes and Joel Ambalu forced the Coalville keeper into another stop.
Coalville dangerman, Tolani Otomola, nearly opened the scoring in the 10th minute after he narrowly beat the offside trap and looked set to get a shot on target, but Cameron Clark did enough to put the striker off.
Belper’s Nathan Curtis put a good chance wide before the visitors had three chances in seven minutes that were either saved or put wide.
When the opener came on 36 minutes it was was coolly taken by Otomola who held off the defender before turning and placing his shot into the far corner, and well out of Max Beardmore’s reach.
On 55 minutes Alex Peterson nearly found the far corner with a shot on the turn, but Max Varnum saved at full stretch to deny the Nailers an equaliser.
The visitors put paid to any hopes of a Belper fight back when Scott McManus knocked in the second goal from close range.
Substitute Peter Cruz made an impression late on for the home side.
